New version of the exam in chemistry. Tests by topic

The Unified State Exam in Chemistry is an exam taken by graduates planning to enter a university for certain specialties related to this discipline. Chemistry is not included in the list of compulsory subjects; according to statistics, 1 out of 10 graduates takes chemistry.

• The graduate receives 3 hours of time to test and complete all tasks - planning and distributing time to work with all tasks is an important task for the test taker.
• Usually the exam includes 35-40 tasks, which are divided into 2 logical blocks.
• Like the rest of the Unified State Examination, the chemistry test is divided into 2 logical blocks: testing (selecting the correct option or options from those proposed) and questions that require detailed answers. It is the second block that usually takes longer, so the subject needs to manage time rationally.

• The main thing is to have reliable, deep theoretical knowledge that will help you successfully complete various tasks of the first and second blocks.
• You need to start preparing in advance in order to systematically work through all the topics - six months may not be enough. The best option– start preparing in the 10th grade.
• Identify the topics that give you the most problems so that when you ask a teacher or tutor for help, you know what to ask.
• Learning to perform tasks typical for the Unified State Exam in chemistry is not enough to master the theory; it is necessary to bring the skills of performing tasks and various tasks to automaticity.
  

• Not always self-study effective, so it’s worth finding a specialist to whom you can turn for help. The best option is a professional tutor. Also, don’t be afraid to ask questions to your school teacher. Don't neglect school education, do your homework assignments carefully!
• There are hints in the exam! The main thing is to learn how to use these sources of information. The student has the periodic table, tables of metal stress and solubility - this is about 70% of the data that will help to understand various tasks.

• Chemistry requires a thorough knowledge of mathematics - without this it will be difficult to solve problems. Be sure to repeat the work with percentages and proportions.
• Learn the formulas needed to solve chemistry problems.
• Study the theory: textbooks, reference books, collections of problems will be useful.
• The best way to consolidate theoretical assignments is to actively solve chemistry assignments. IN online mode you can solve in any quantity, improve your problem solving skills different types and level of difficulty.
• Controversial issues in assignments and errors are recommended to be sorted out and analyzed with the help of a teacher or tutor.

Tips for preparing for the Unified State Exam in chemistry on the website website

How to competently pass the Unified State Exam (and Unified State Exam) in chemistry? If you only have 2 months and you’re not ready yet? And don’t be friends with chemistry...

It offers tests with answers for each topic and task, by passing which you can study the basic principles, patterns and theory found in the Unified State Exam in chemistry. Our tests allow you to find answers to most questions encountered in the Unified State Exam in chemistry, and our tests allow you to consolidate the material, find weak points, and work on 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 it is worth going through. If everything is very bad and 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 minimum quantity points you want to score, this will allow you to understand how many tasks you must solve accurately to get the score you need.
   Naturally, take into account that everything may not go so smoothly and solve it as best you can. larger number tasks, or better yet, everything. 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. Select only the exam you are interested in and solve the corresponding test. About 20 solved tasks guarantee that you will meet all types of problems. 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 don’t know how to solve a task, use the search on our website. 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. At the same time, we repeat the third point for everyone on our website, starting with.
4. When the first part is given to you at least at an average level, you begin to decide. If one of the tasks is difficult, and you made a mistake in completing it, then return to the tests on this task or the corresponding topic with tests.
5. Part 2. If you have a tutor, focus on studying this part with him. (provided that you are able to solve the rest at least 70%). If you started part 2, then you should score a passing grade without any problems 100% of the time. 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 to part 2. The key to success is solving as many tasks as possible, just like in part 1.

But there is no need to be afraid that you will have to memorize a huge number of numbers - during the Unified State Exam, each student will be given “tips” that will reduce this problem to nothing, namely:

• Periodic table
• Solubility table
• Metal stress series.
