Changes in the demonstration versions of the exam in chemistry

Demonstration versions of the exam in chemistry for grade 11 for 2002 - 2014 consisted of three parts. The first part included tasks in which you need to choose one of the proposed answers. The tasks from the second part were required to give a short answer. To the tasks from the third part it was necessary to give a detailed answer.

In 2014 in demonstration version of the exam in chemistry the following changes:

• all calculation tasks, the performance of which was estimated at 1 point, were placed in part 1 of the work (A26-A28),
• subject "Redox Reactions" tested with assignments AT 2 And C1;
• subject "Hydrolysis of salts" checked only with the task AT 4;
• a new task has been included(in position AT 6) to check the topics "qualitative reactions to inorganic substances and ions", "qualitative reactions of organic compounds"
• total number of jobs in each variant was 42 (instead of 43 in the work of 2013).

In 2015, there were fundamental changes have been made:

Option became be in two parts(part 1 - short answer questions, part 2 - open-ended questions).

Numbering assignments has become through throughout the variant without letter designations A, B, C.

Was the form of recording the answer in tasks with a choice of answers has been changed: the answer has become necessary to write down the number with the number of the correct answer (and not mark with a cross).

Was reduced number of tasks basic level difficulty from 28 to 26 tasks.

Maximum score for completing all the tasks of the examination paper in 2015 became 64 (instead of 65 points in 2014).

• The grading system has been changed. tasks for finding the molecular formula of a substance. The maximum score for its implementation - 4 (instead of 3 points in 2014).

IN 2016 year in demo in chemistrysignificant changes have been made compared to the previous year 2015 :

Part 1 changed the format of tasks 6, 11, 18, 24, 25 and 26 basic level of difficulty with a short answer.

Changed the format of tasks 34 and 35 increased level of complexity : these tasks now require you to match instead of selecting multiple correct answers from a suggested list.

The distribution of tasks by difficulty level and types of skills being tested has been changed.

In 2017 compared to demo version of 2016 in chemistrythere have been significant changes. The structure of the examination paper has been optimized:

Was changed the structure of the first part demo version: tasks with a choice of one answer were excluded from it; tasks were grouped into separate thematic blocks, each of which began to contain tasks of both basic and advanced levels of complexity.

Was reduced the total number of tasks up to 34.

Was grading scale changed(from 1 to 2 points) completing tasks of a basic level of complexity that test the assimilation of knowledge about the genetic relationship of inorganic and organic matter(9 and 17).

Maximum score for the completion of all tasks of the examination paper was reduced to 60 points.

In 2018 in demo version of the exam in chemistry compared with demo version of 2017 in chemistry the following changes:

Was task 30 added high level of complexity with a detailed answer,

Maximum score for the completion of all tasks of the examination work remained without change by changing the scale for grading tasks in part 1.

IN demonstration versions of the Unified State Exam 2019 - 2020 in chemistry compared with demo version of 2018 in chemistry there were no changes.

For 2-3 months it is impossible to learn (repeat, pull up) such a complex discipline as chemistry.

There are no changes in KIM USE 2020 in chemistry.

Don't delay your preparation.

1. Before starting the analysis of tasks, first study theory. The theory on the site is presented for each task in the form of recommendations that you need to know when completing the task. guides in the study of the main topics and determines what knowledge and skills will be required when completing the USE tasks in chemistry. For the successful passing of the exam in chemistry, theory is the most important thing.
2. Theory needs to be backed up practice constantly solving problems. Since most of the errors are due to the fact that I read the exercise incorrectly, I did not understand what is required in the task. The more often you solve thematic tests, the faster you will understand the structure of the exam. Training tasks developed on the basis of demos from FIPI give them the opportunity to decide and find out the answers. But do not rush to peek. First, decide for yourself and see how many points you have scored.

Points for each task in chemistry

• 1 point - for tasks 1-6, 11-15, 19-21, 26-28.
• 2 points - 7-10, 16-18, 22-25, 30, 31.
• 3 points - 35.
• 4 points - 32, 34.
• 5 points - 33.

Total: 60 points.

The structure of the examination paper consists of two blocks:

1. Questions that require a short answer (in the form of a number or word) - tasks 1-29.
2. Tasks with detailed answers - tasks 30-35.

3.5 hours (210 minutes) are allotted to complete the examination paper in chemistry.

There will be three cheat sheets on the exam. And they need to be dealt with.

This is 70% of the information that will help you successfully pass the exam in chemistry. The remaining 30% is the ability to use the provided cheat sheets.

• If you want to get more than 90 points, you need to spend a lot of time on chemistry.
• To successfully pass the exam in chemistry, you need to solve a lot: training tasks, even if they seem easy and of the same type.
• Correctly distribute your strength and do not forget about the rest.

Dare, try and you will succeed!

Chemistry is an optional exam that graduates choose when entering higher educational establishments for the respective specialties. Out of ten students, one passes this particular subject at will.

Students were given three hours to test. During this time, they have to deal with 40 tasks. They are traditionally divided into two parts: in the first there are 35 questions, in the second - 5 more.

All tasks are divided into three levels of difficulty:

• A - simple questions: choosing the correct answer from the options offered;
• IN - elevated level difficulties. These are tasks for which the student independently forms a short answer;
• C - the most difficult tasks, involving detailed explanations on the topic.

The simplest questions give the graduate one point each if he answers them correctly. For tasks of type B, they already give 1 or 2 points, depending on their complexity, and the maximum that can be scored is 18. The most difficult tasks are estimated at 3-4 points.

Innovations in 2016

The exam in chemistry is considered a difficult exam. But FIPI decided that it was possible to make life a little more difficult for graduates. Therefore, in 2016, the number of the simplest questions decreased: there were 26 of them against 28.

To prepare 11th graders for a knowledge test, FIPI offers fresh demo materials. They clearly demonstrate the structure of the upcoming exam in chemistry. It is also worth trying your knowledge in free tests. They are based on data from previous years. For a successful passage of the exam, do not forget about textbooks, since the tests do not raise all the topics that are included in the exam.

Minimum passing score

In 2016, the minimum passing score for the Unified State Examination in Chemistry will be 64 points. With this indicator, you can enter the university.

Tips for preparing for the exam in chemistry on the site site

How to correctly pass the exam (and OGE) in chemistry? If the time is only 2 months, and you are not ready yet? Yes, and do not be friends with chemistry ...

It offers tests with answers for each topic and task, passing which you can learn the basic principles, patterns and theory found in the exam in chemistry. Our tests allow you to find answers to most questions found in the exam in chemistry, and our tests allow you to consolidate the material, find weak spots and work out the material.

All you need is the Internet, stationery, time and a website. It is best to have a separate notebook for formulas / solutions / notes and a dictionary of trivial names of compounds.

1. From the very beginning, you need to assess your current level and the number of points that you need, for this you should pass. If everything is very bad, but you need excellent performance, congratulations, even now all is not lost. You can train yourself to pass successfully without the help of a tutor.
   Decide on the minimum number of points you want to score, this will allow you to understand how many tasks you must solve exactly in order to get the score you need.
   Naturally, keep in mind that things may not go so smoothly and solve as many tasks as possible, and preferably all. The minimum that you have determined for yourself - you must decide ideally.
2. Let's move on to the practical part - training for the solution.
   Most effective method- next. Choose only the exam you are interested in and solve the corresponding test. About 20 solved tasks guarantee a meeting of all types of tasks. As soon as you begin to feel that you know how to solve every task you see from beginning to end, proceed to the next task. If you do not know how to solve any task, use the search on our site. There is almost always a solution on our website, otherwise just write to the tutor by clicking on the icon in the lower left corner - it's free.
3. In parallel, we repeat the third paragraph for everyone on our site, starting with.
4. When the first part is given to you at least at an intermediate level, you begin to decide. If one of the tasks does not lend itself well, and you made a mistake in its implementation, then you return to the tests for this task or the corresponding topic with tests.
5. Part 2. If you have a tutor, focus on learning this part with him. (assuming you are able to solve the rest at least 70%). If you started part 2, then you should gain a passing score without any problems in 100% of cases. If this does not happen, it is better to stay on the first part for now. When you are ready for part 2, we recommend that you get a separate notebook where you will write down only the solutions of part 2. The key to success is solving as many tasks as possible, just like in part 1.
