Is it difficult to pass the Unified State Exam in physics, social studies, biology and chemistry? “When I decided that I would take the Unified State Exam in chemistry, even the ammonium ions were surprised.

The Unified State Exam (USE) in chemistry is not included in the list of mandatory exams. It is worth taking chemistry only if your choice of future profession lies in the field of medicine, construction, chemical or biotechnology.

Schoolchildren often ask teachers the question: “Is it difficult to pass the Unified State Exam in chemistry?” It is definitely not easy to answer, but learning a little more about the examination process is worth it to everyone who has chosen this discipline.

The exam consists of 40 tasks, which are divided into three parts - A, B and C.

Tasks A1-A26 belong to the basic level, and the correct answer to each question brings the student one primary point. There are four possible answers, from which you need to choose the correct one.

Let's look at how to solve these types of tasks.

Job type Possible error Action
Standard simple question Hasty answer

Read the entire question to the end, discard the obviously incorrect options and choose the correct answer

Question with denial The answer to the question is exactly the opposite

Don't forget about denial

Group selection

Focusing on the first thing in the group All elements listed in the group must meet the task conditions

Two judgments

Ignorance of some exceptional properties of a particular thing

Remember the exception rules in chemistry

General recommendations:

  • solve tasks in three stages: in the first stage, discard difficult questions and solve only obvious ones; on the second - think and remember the exception rules; and on the third, if there are still unsolved tasks, use your intuition and try to guess the correct answer;
  • remember the cheat sheets: the periodic table, the solubility table and the voltage series;
  • if it seems to you that there are several correct options in the list of answers, re-read them several times: perhaps you missed a denial or facts that are possible in principle, but are not used in practice;
  • Remember the special properties of some substances and exceptions to the rules.

Doing Part B: Going Deep and Focusing

B1-B9 - this is how tasks of an increased level of complexity are marked, where you need to write down a short answer. Each completed task is scored from 1 to 2 points, and in total you can get 18 primary points for correctly completed tasks.

There is a gradation of tasks by type, and, accordingly, its own nuances of implementation.

Job type Possible error Action

Matching tasks

The desire to apply every proposed answer Carefully re-read each proposed answer option. Please note that the letters in the answer may be repeated, and some of the proposed options may not be applicable to solve the problem

Group selection

Getting confused in the names of compounds of each group due to the need to compare several parameters at once

To answer correctly, it is necessary to take into account the interactions of things. This is where eliminating unnecessary options can help.

Correspondences between substances and the coefficient of the ionic equation

Forget about coefficient 1, which is not written. When moving from the full ionic equation to a reduced one, many people forget that coefficients can also be reduced if they can be divided by the same number.

Remember the rules for solving ionic equations and reducing coefficients. Do not confuse the numbering of answer options with answer values

Multiple Choice Questions

Use only one option or all at once.

Recording selected options in a chaotic order

Remember that there is a special field for preliminary calculations, and only after you have finally solved the task, write down the options in ascending order on the answer form.

As a rule, in this type of task there are 3 correct answer options.

Calculation problems Rounding errors Use the calculation field and write down only the correct answer

General tips for solving problems in Part B:

  • do not rush to write down answers on the test form;
  • If you are in doubt about a multiple choice task, it is better to write fewer answer options.

Part C: maximum attention

Tasks of the most difficult level of the Unified State Exam in chemistry - C1-C5. There are only five of them, for each you need to give a full, detailed answer. Problems are worth 3 or 4 points, and the maximum you can get for the entire part C is 18 points.

If you get stuck on the first two parts, you won’t have enough time to solve the third. Look at the main types of tasks in Part C and the mistakes that students most often make.

Job type Possible error Action
Equations of redox reaction Even when solving the equation correctly, many people forget to indicate the oxidizing agent. Determine the missing reaction compounds and oxidation states, apply the standard electronic balance algorithm. Double-check the answer you provided.
Equations of possible reactions for a set of inorganic substances Many people forget to double-check the recorded answer. Write down only those equations in which you are 100% sure, because only the first 4 are counted
"Thought Experiment" Some examinees skip this task because the answer is unclear. 1) draw up a reaction scheme; 2) decipher the diagram, replacing the designations with specific formulas; 3) write the reaction equations, placing all the coefficients. Do at least one of the listed steps correctly and it will earn you a point
Chain of transformations of organic substances

Do not indicate by-products in addition to the main products. Examinees do not take into account the reaction conditions and write equations without structural formulas

Consider the sequence of reactions and write the formulas correctly. Remember about complex reactions (oxidation with permanganate, electrolysis of solutions of carboxylic acid salts, interaction of halogen derivatives with alcoholic and aqueous alkali solutions, etc.)
Combined task Errors in nomenclature and reaction equations. Often examinees do not understand the difference between phosphate and phosphide, nitrite and nitride Write down all the results of reactions at each stage of solving the problem and take them into account in subsequent calculations using the reaction equation
Determining the formula of a substance In problems with combustion products, hydrogen is lost, which is part of the hydrogen halides Test yourself to see if there are more molecules or atoms. Don't get carried away with excessive rounding. Remember to write down structural formulas
  • be sure to perform the calculation using the reaction equation in MOLES, otherwise the solution to the problem will not be counted;
  • complete at least part of the task: in this case you have a chance to earn at least a few extra points;
  • Write down your answers as legibly as possible to avoid losing points due to carelessness.

At school I took chemistry for show, nothing more. In the 9th grade there was no this subject for six months, and the remaining six months were taught... by a fireman. In grades 10-11, chemistry went like this: I didn’t go to it for half the semester, then I handed in three downloaded presentations, and they gave me a proud “five” because I had to travel 12 km to school 6 days a week (I lived in a village, studied in city) was, to put it mildly, lazy.

And so, in 11th grade, I decided to take chemistry. My knowledge of chemistry was zero. I remember being surprised by the existence of the ammonium ion:

– Tatyana Alexandrovna, what is this? (Pointing to NH4+)

– Ammonium ion, formed when ammonia is dissolved in water, similar to potassium ion

- I see it for the first time

Now about Tatyana Alexandrovna. This is my chemistry tutor from October to June of the 13/14 academic year. Until February, I just went to her, sat my pants, listened to boring theory on general and inorganic chemistry. Then February came and I realized that the Unified State Exam was too close... What to do?! Get ready!

Subscribe to "PU" intelegram . Only the most important things.

Little by little, deciding on options (at first without organics), I prepared. At the end of March we finished studying INORGANICS, there was a sample that I wrote for 60 points and for some reason I was very happy. And the goal was powerful, above 90 points (my department needed a lot of points). And all knowledge of organics was limited to the homological series of methane.

In April-May, a difficult task lay ahead: to learn all the organic matter. Well, I sat until 11 at night, until my eyes were drooping, solving tests, getting better at it. I remember that on the last evening before the exam I studied the topic of “amines”. In general, time is running out.

How the exam itself went: in the morning I solved one option (to turn on my brain) and came to school. It was the most anxious hour of my life. Firstly, chemistry was the most difficult exam for me. Secondly, immediately after chemistry they were supposed to announce the results of the Unified State Exam in Russian. I barely had enough time in the exam, although I didn’t have enough time to complete problem C4. I passed with 86 points, which is not bad for several months of preparation. There were errors in part C, one in B (just about amines) and one controversial error in A, but you cannot appeal against A.

Tatyana Aleksandrovna reassured me, saying that she just couldn’t wrap her head around it yet. But the story doesn't end there...

I didn’t enter my faculty last year. Therefore, the decision was made: it will work the second time!

I started preparing right from the first of September. This time there was no theory, just solving tests, the more and faster the better. Additionally, I studied “complex” chemistry for the university entrance exam, and for six months I took a subject called “general and inorganic chemistry,” which was taught by Olga Valentinovna Arkhangelskaya herself, the organizer of the All-Russian Olympiad in Chemistry. Six months passed like this. Knowledge of chemistry has increased significantly. I came home in March, complete isolation. Continued preparations. I was just solving tests! A lot of! There are about 100 tests in total, some of them several times. Passed the exam with 97 points in 40 minutes.

1) Be sure to study the theory, and not just solve tests. I consider the best textbook to be “Principles of Chemistry” by Eremin and Kuzmenko. If the book seems too large and complicated, then there is a simplified version (which is enough for the Unified State Exam) - “Chemistry for high school students and those entering universities”;

2) Pay special attention to the topics: production, safety precautions, chemical glassware (no matter how absurd it may sound), aldehydes and ketones, peroxides, d-elements;

3) After solving the test, be sure to check your mistakes. Don’t just count the number of errors, but look at which answer is correct;

4) Use the circular solution method. That is, you solved a collection of 50 tests, solve it again in a month or two. This way you will consolidate material that is little remembered for you;

5) There will be cheat sheets! Write cheat sheets, always by hand and preferably small. This way, you will remember problematic information better. Well, no one forbids using them during the exam (only in the toilet!!!), the main thing is to be careful.

6) Calculate your time along with the registration. The main problem of the chemistry exam is lack of time;

7) Formulate tasks (preferably) the way they are presented in collections. Instead of "nude" write "n", for example.

Told by Egor Sovetnikov

In the section on the question: Is it difficult to pass the Unified State Exam in chemistry and biology in 11th grade? given by the author Peculiarity the best answer is I rented them out last year. If you understand these subjects, then everything is quite simple.
There are three parts to the Unified State Exam in Biology. The first one is pretty easy. When choosing one of 4 answers, half are immediately discarded, and between the remaining two you will need to think a little)
In the second part there will be correspondences (connect the first and second columns in pairs), distribution of words into groups (for example, which features relate to reptiles, which to amphibians) and other similar tasks. The third part consists of questions that will need to be answered. There may also be tasks on cytology and genetics. I highly recommend repeating their solutions, since I was a little confused about genetics during the exam)
The structure of chemistry exams is similar to biology. Only in the third part there is no need to answer questions. There will be problems that require solutions. And the tasks, I admit, are not easy. It would be a good idea to review the redox equations. Oh yes! And almost half of the tasks in the entire exam are based on organic chemistry. If you understand it well, you will pass for sure)
Good luck with exams!)

There is hardly a final exam more difficult than the OGE or the Unified State Exam in chemistry. This subject must be taken by future biologists, chemists, doctors, engineers and builders. Today we will talk about what you need to know in order to get high scores, and what benefits are best to use.

Books and manuals for preparation

Unified State Examination and Unified State Examination experts recommend relying on specialized-level textbooks when preparing. The material in a standard basic textbook is not enough to successfully pass the exam. Practice shows that schoolchildren who have taken a specialized chemistry course feel quite confident during the exam. Several such textbooks have been written, but in terms of content and presentation they are approximately the same.

We recommend getting a collection of standard exam tasks - the official publication of FIPI (with a hologram) and a couple of books by other authors. They analyze tasks in detail, show ways to solve them, and provide algorithms and answers for self-control. The more options you solve, the greater your chances of passing the exam.

Repetition is the mother of learning

This is an important component of quality training. Chemistry is a complex science about matter; without knowing the basic topics of the initial course, you will not understand more complex ones. Of course, there may not be enough time to repeat the entire program, so it is better to pay more attention to precisely those issues that cause the most difficulty.

According to teachers at the Merlin Center, schoolchildren more often make mistakes in assignments related to the following topics:

  • mechanisms of molecular bond formation;
  • hydrogen bond;
  • patterns of chemical reactions;
  • physicochemical properties of solutions, electrolytic dissociation, reactions in electrolyte solutions;
  • the effect of solution dilution on the degree of dissociation (Ostwald's dilution law);
  • hydrolysis of salts;
  • atmospheric compounds;
  • main classes of compounds;
  • industrial production and scope.

The same standard exam tasks and tests will help you identify gaps. Does not work? Ask your chemistry teacher for help or sign up for prep courses.

Conduct experiments

Chemistry is a science based on real experiments with substances. Experiments will help you better understand a particular topic. To do this, it is not necessary to buy a set of reagents and laboratory supplies. There are many interesting, well-produced videos on the Internet about chemical reactions. Don't be lazy to find them and look.

Be careful during the exam!

Most mistakes are made by children precisely because of inattention. Train yourself not to miss a single word when reading the task, pay attention to the wording and how many answers there should be.

  • Read the question to the end, think about its meaning. There is often a little clue hidden in the wording.
  • Start with easy questions where you have no doubt about the correctness of the answers, then move on to more complex tasks where you need to think.
  • If a question is too difficult, skip it, don't waste time, you can come back to it later.
  • The tasks are not related to each other, so focus only on the one you are doing at the moment.
  • If you have difficulty, first try to eliminate obviously incorrect answers. It’s easier to choose an option from the remaining two or three than to get confused among five or six answers.
  • Be sure to leave time to check your work so that you can quickly review assignments and correct any mistakes. An unfinished word or number may cost you a point.

Chemistry is a difficult subject, and it is best to prepare for the exam under the guidance of an experienced teacher; it is not recommended to count on the fact that you will cope with such an important task. Only a teacher can point out “inconspicuous” mistakes and help you fill in the gaps and explain complex material in simple, accessible language.

The Unified State Exam is a centralized exam conducted in Russian educational institutions. Thanks to control measuring materials, it helps to assess the quality of students' preparation. In this article we will learn how to pass the Unified State Exam, which exams to take and how to get 100 points.

Since 2009, the Unified State Exam has been a form of final exams at a lyceum or school, as well as a form of entrance exams to universities. The list of compulsory disciplines is represented by mathematics and the Russian language. Other items are chosen at your discretion. This could be a foreign language, literature, computer science, physics, geography and others.

The number of optional subjects selected for delivery is not limited. When compiling a list of disciplines, students are guided by the requirements of the higher educational institution chosen for admission.

They take the Unified State Exam from May to June. The legislation provides for early and additional periods of delivery. The first occurs in April, and the second in July. Graduates of the current year who:

  • Conscripted into the army;
  • Going to a Russian or international Olympiad;
  • Are sent for treatment abroad;
  • They graduate from a Russian-language school in a country with a difficult climate.

The additional period provides for the passing of the Unified State Exam by foreign citizens, graduates of previous years, and graduates of primary vocational education.

On Russian territory, the conduct of the state exam is controlled by the Federal Service for Supervision in the Field of Science and Education with the support of executive authorities of Russian constituent entities. If testing is carried out abroad, in addition to Rosobrnadzor, the founders of an educational institution that has passed state accreditation participate in the procedure.

The evaluation of the final certification results is based on a 100-point system. For each discipline, a minimum score level has been established, overcoming which confirms that the student has mastered the school educational program. Unified State Exam results are considered valid for 4 years following the year in which the student received them.

If the result of a participant in the final certification in a compulsory academic discipline does not reach the established minimum level, a retake is provided in an additional period. If the second pass was unsatisfactory, you are allowed to try your luck again, but in the fall. In the case of an elective subject, everything is more complicated. A certification participant who does not score the minimum number of points is forced to wait a year to retake the exam.

Important! State testing participants who are removed from the classroom for misconduct, cheating, or cell phone use are subject to severe penalties. Their results are canceled, as is the right to retake an additional period. Re-taking is allowed after a year. So there is no point in cheating in the exam.

How to pass the Unified State Exam if you don’t know anything

Pedagogical practice shows that schoolchildren, instead of preparing for exams, relax and chat with friends. In the old days, in the absence of knowledge, quickly made cheat sheets came to the rescue of lazy schoolchildren.

The introduction of the Unified State Exam has significantly complicated the procedure for passing state testing. Commission members closely monitor each student, and the use of cheat sheets and electronics is severely punished. How to successfully pass certification if during the preparatory period things did not come to study? I have some advice on this matter.

  • If Judgment Day is still a few weeks away, start preparing. Use the services of a tutor and pay special attention to solving trial tasks. Learning the basics is the key to success if you don't know anything.
  • If the test is in a few days and you don’t have time to study the material, skim the pages of the textbook. It is possible that at an important moment visual memory will come to the rescue. I talked about how to improve memory in one of the articles.
  • When test day arrives, stay confident, grab your pass, passport, some pens and pencils, a ruler and eraser, and go. Also make sure that you have a bottle of mineral water and a chocolate bar in your backpack.
  • Once in the classroom, choose a seat you like, sit comfortably at the table and take a few deep breaths. Don't worry. You attended classes throughout the year and probably something remained in your memory.
  • After receiving the package with forms and assignments, slowly fill out the registration information. When the teachers give the go-ahead, get down to business. You have 4 hours at your disposal.
  • Start with what you know. Having completed easy tasks, switch to more complex tasks. Even if there are difficulties with the decision, do not rush to leave the audience. Sit until the last minute. There are often cases when the correct answer comes at the last moment.

People who are well acquainted with the procedure for passing the final certification claim that many schoolchildren greatly exaggerate the complexity of the situation and lower their level of knowledge in their thoughts. It's all due to severe stress. If you strive to achieve a goal, curb your panic, calm down and get ready to work. This is the secret of success.

What Unified State Examinations are taken in 11th grade in 2019?

According to available information, to obtain a certificate in 2019, passing tests in 11th grade in mathematics and the Russian language is not enough. Now you need to pass an additional optional exam.
If you do not plan to study at university, opt for a simple school discipline.

The full list of subjects available for choice is presented in literature, chemistry, physics, history, geography, social studies, computer science and foreign languages.

Among the innovations in 2019 is the absence of a test part, with the exception of foreign languages. Therefore, prepare responsibly as the written exam is more difficult than the multiple choice test.

Rumors have appeared that in 2019, grades for the Unified State Exam will affect the marks on the certificate, either down or up. There are also plans to make the Russian language exam more difficult. This year, graduates will face more challenging assignments. As for the essay and its evaluation criteria, there are no changes provided.

The list of the most popular exams in universities is represented by the exact sciences, including computer science, chemistry and physics. This is due to a shortage of qualified engineers in the country and a surplus of economists and financiers.

Periodically visit the portal of the Federal Institute of Pedagogical Measurements. Documents related to passing the Unified State Exam are regularly published here. There is also a table of changes that will help you get a complete impression of the innovations.

Which Unified State Exams do you need to take for admission to universities?

It is impossible to enter an institute or university without a certificate of passing the Unified State Exam. It is important that a graduate planning to become a student at one of the universities must pass exams to enroll. In this part of the material I will consider several popular areas and help in choosing school subjects to take. And remember that mathematics and Russian are compulsory.

  1. If you are planning to enter a medical school, prepare to take the Unified State Exam in chemistry and biology. Dentists need to pass a physics exam. Some universities require a foreign language test.
  2. Those who want to study to become a psychologist need to pass an exam in biology, which is considered a major subject. Depending on the chosen direction, sometimes you need Unified State Examination results in a foreign language. It all depends on the university.
  3. If you see yourself as a teacher, prepare to take the relevant subject. In particular, to enroll in physics and mathematics, in addition to the main exams, you need physics. For a chemist-biologist, there is a test in chemistry and biology, and so on.
  4. There are many faculties available to graduates who want to study at Moscow State University. For example, if you choose the department of “Recreational Geography and Tourism”, take the Unified State Exam in Geography, and the department of “Philosophy” will require natural science.
  5. MIPT also has requirements. To enter this university you need computer science or physics. It all depends on the direction chosen by the graduate.
  6. Educational institutions of the Ministry of Internal Affairs have special requirements for applicants. They give preference to graduates who have passed the Unified State Exam in social studies, history, physics or biology, depending on the field. Each graduate will also have to pass sports standards.
  7. For those who want to become a student at the Military Space Academy, I recommend concentrating on preparing to take the Unified State Exam in physics. Without this major subject, as well as without sports standards, the university will not accept you.

In conclusion, I would like to add that each educational institution has its own requirements for the Unified State Examination results. If you have already decided on the university and faculty, contact the admissions committee for detailed information. This will protect you from a life-changing mistake.

What you need to know to pass the Unified State Exam with 100 points

Graduates seeking to enter the university prepare to take the Unified State Exam with all responsibility. Many aim to achieve 100 marks in all subjects. It is not surprising, because the maximum score indicates that the graduate has knowledge from the school curriculum at the highest level. Such results open the way to any of the universities.

Many people believe that it is impossible to pass the Unified State Exam with 100 points. In reality this is not the case. With timely and proper preparation, any student has the opportunity to pass tests and get the highest score.

Let's look at the nuances of pre-exam preparation. This set of simple recommendations will help you pass the Unified State Exam with 100 points in the following subjects: social studies, biology, history, Russian and foreign languages, mathematics, physics and chemistry. Let's get started.

  • Stock up on textbooks for the subjects you have chosen to take from sixth to eleventh grade. During preparation, pay special attention to the topics that cause the most difficulty.
  • Study the exam questions to get an idea of ​​the questions you will face in the exam. Keep a diary, make a preparation schedule. For each item of your plan, allocate enough time to study the material in depth.
  • Take notes. When reading textbooks, write down basic concepts and terms. Drawings and diagrams will increase the efficiency of memorization. Between the outlined topics, leave free space to record new or additional information on important issues.
  • Teachers like it when students talk. Learn to give detailed answers, give arguments, give explanations, use terms. Meaningful answers will increase your chances of receiving the highest score.
  • Visualize new information. As practice shows, cramming is a pointless waste of time. Delve into the topic you are studying, take advantage of associative memory, and imagine images.
  • Get a test guide for your chosen subjects and spend a lot of time working on them. Self-study will help you master the material and hone your skills in solving standard problems.
  • Start preparing early. Regardless of the subject you choose, you will have to study a huge amount of information. It takes time to master such a volume. Start preparing at least a year in advance. To improve the quality of knowledge, I advise you to use the services of a tutor or sign up for thematic courses.
  • Harness time. A certain amount of time is allocated for testing in school subjects. Complete all tasks if you take into account the time frame. At the same time, in pursuit of 100 points, you will have to solve problems quickly and correctly. To improve your skills, I recommend using the demo version of the Unified State Exam on the department’s website.

If you have set a goal of 100 points in all subjects, be prepared for labor-intensive and lengthy preparation. The recommendations outlined will make your life easier and will be a good help.

Answers on questions

Do I need to take the Unified State Exam after college or technical school?

At the initial stage of its introduction, the Unified State Exam evoked a lot of different emotions among college and technical school graduates. This is justified by state testing receiving the status of entrance exams to Russian higher educational institutions. What does it mean?

Having a certificate of passing the final certification opens the way to any university if the test results meet the requirements established by the university. People who graduated from school before 2009 do not have such a document. And if they continued their studies at a college or technical school, after graduation they are interested in whether they need to pass the Unified State Exam to enter a university? The further development of the situation has two scenarios.

  • A graduate of a college or technical school who wishes to continue studying at a university in accordance with the specialty received will not have to pass the state exam. To enroll in a university, it is enough to pass a specialized exam.
  • If a student received one specialty in college or technical school, and at the university wants to master another profession, there are two ways to solve the problem. The first involves passing the Unified State Exam, and the second involves passing entrance exams, as was the case before.

The introduction of new rules deprived graduates of technical schools and colleges of some advantages that help them to be guaranteed admission to university. But having a diploma from a secondary educational institution still gives the student more confidence.

How to pass the Unified State Exam for a graduate of previous years

There are often cases when a desire to undergo state certification arises from a graduate who graduated from school in previous years. This is good, because it is never too late to get a higher education diploma. In this part of the material we will talk about the intricacies of passing the Unified State Exam by graduates of previous years.

Passing the Unified State Exam for a former graduate has a peculiarity - you do not have to take compulsory subjects, except in cases where mathematics and Russian are needed for enrollment in the chosen specialty.

Graduates of previous years take the Unified State Exam ahead of schedule or along with the main wave. To do this, an application to take the exam is submitted in advance to the municipal education authority, indicating the main and additional disciplines, a passport and a certificate.

In addition to personal information, if you have studied for a long time, the application indicates the name of the completed educational institution, details, form of study and date of receipt of the diploma. Graduates from other countries who wish to continue their studies at a Russian university must present a foreign passport, the original document of education with a certified translation from a foreign language.

To obtain admission to the final certification, an essay is written. This innovation does not apply to graduates of previous years. The work is written solely at will. However, some universities award several points for an essay upon admission.

Graduates of previous years take the Unified State Exam at the place of application. If you live in another city, you do not need to return to your hometown to obtain a certificate.

In the article, we looked at how to pass the Unified State Exam if you don’t know anything, gave tips for getting 100 points and answered popular questions. Rational preparation combined with a positive psychological attitude, strong motivation and absolute calm will help you get the best results.

Don't panic, and on the morning before the certification, concentrate on mental preparation, and not on skimming through textbooks. Such actions only escalate the situation.
