When a student of grade 11 begins to prepare for the exam in computer science, as a rule, he prepares from scratch. This is one of the differences between the exam in computer science and exams in other subjects.

In mathematics, the knowledge of a high school student is definitely not zero. In Russian, even more so.

But in computer science, the situation is much more complicated. What is studied at school in the classroom has nothing to do with the preparation program for the exam in computer science.

What is the USE in Informatics?

The USE control test in computer science contains 27 tasks, which relate to a variety of topics. These are number systems, this is Boolean algebra, algorithmics, this is programming, modeling, elements of graph theory.

The USE in Informatics covers a very wide range of information. Of course, the exam will only need the basics, but these are the basics of important and modern topics.

Preparing for the Unified State Exam in computer science from scratch implies that the student did not study any of these topics at school. Usually it is!

For example, such a topic as Boolean algebra, or the algebra of logic, is included in the exam in computer science. But it is not studied in schools, even in specialized ones. She is neither in the course of school computer science, nor in the course of mathematics. The student has no idea!

And therefore, almost none of the students solves the famous problem on systems of logical equations. This task in the Unified State Examination in Informatics is number 23. Let's say more - teachers often recommend that high school students not try to solve this problem at all, and not even look at it, so as not to waste time.

Does this mean that task 23 from the Unified State Examination in Informatics is not solved at all? Of course not! Our students regularly solve it every year. In our course of preparation for the Unified State Examination in Informatics, from many topics, we take only what is required for the exam. And we pay maximum attention to these tasks.

Why does the school not prepare for the exam in computer science?

This is due to the fact that computer science is not a compulsory subject. The Ministry of Education does not provide any standards and programs. Therefore, teachers at computer science lessons give schoolchildren completely different material - who can do what. Moreover, in some schools there are no computer science lessons at all.

What do high school students usually do in computer science classes? Do they play shooting games?

Fortunately, at school, in computer science lessons, schoolchildren are still doing not nonsense, but quite useful things. For example, they study Word and Escel. In life, this will come in handy, but, unfortunately, it is absolutely useless for passing the exam.

Moreover, the guys study Word at a serious level, and some even pass exams in computer layout and receive a certificate of a typesetter. Some schools teach 3D modeling. A lot of schools give web design. This is a wonderful topic, useful in the future, but it has absolutely nothing to do with the exam! And coming to our courses, the student really prepares for the exam in computer science from scratch.

A similar situation is with high school students of specialized lyceums. Strong profile lyceums honestly teach programming in computer science lessons. The guys come out of there as good programmers. But after all, in the USE in computer science, only 5 tasks are somehow related to programming, and of them exactly one task in the USE version is devoted to writing a program! The result is a maximum of 6 tasks for the exam in computer science.

How much time does it take to prepare for the exam in computer science from scratch?

There is good news! You can prepare for the exam in computer science from scratch in one year. It's not easy, but it's possible, and our students prove it every year. The course of preparation for the exam in computer science is not very big. You can take courses once a week for 2 hours. Of course, you need to actively do your homework.

But there is one amendment. If a student has never done programming before grade 11, it is hardly possible to fully master programming in a year. Therefore, task No. 27 of the USE variant in computer science will remain unsolved. She is the most difficult.

It is especially difficult to prepare for the exam in computer science from scratch for those students who have never been familiar with programming at all and do not know what it is. This area is quite specific, so programming training needs to be given a lot of time and solve a huge number of tasks.

In our courses, we make sure to analyze all the typical programming tasks. And not once during the exam did the programming problem come as a surprise to our students - they were all sorted out during the courses. And only task 27 is left out for those who did not do programming at all until the 11th grade.

Coming to our computer science courses, students and parents are sometimes surprised not to see computers in the classroom. They think that since they came to prepare for the exam in computer science, then there should be computers on the tables. But they are not! To what extent is it necessary to have laptops and computers when preparing for the exam in computer science?

This is a feature of the exam in computer science. There will be no computer for the exam! And yes, it will be necessary to solve tasks with a pen on a piece of paper, because it is in this format that the Unified State Examination in Informatics is now taking place. This is a real problem for those who rent it.

Even high school students from specialized lyceums, who are good at programming, may be helpless at the exam in computer science. They, of course, program on computers, that is, in a special environment. But what happens when there is no computer? And not only schoolchildren - even professional programmers can write a program on paper with great difficulty. Therefore, we are preparing for such a complex format right away. We deliberately do not use computers and laptops when preparing for the Unified State Exam in computer science - according to the rule "It is hard in learning, easy in battle."

For several years now, there have been rumors that the Unified State Exam in computer science will be transferred to a computer form. They promised to do it in 2017, but they didn't. Will they do it in 2018? We don't know yet. If such an exam format is introduced, it will be much easier to prepare for the exam in computer science from scratch.

So, a year of active preparation for the exam in computer science from scratch, and your result is 26 tasks out of 27 possible. And if you are at least a little familiar with programming, then all 27 out of 27. We wish you to achieve such a result in the exam!

And once again I recommend for the preparation of theoretical material and my book "Computer science. Author's course of preparation for the exam " where the practice of problem solving is given.

Tell your friends!

With the modern world of technology and the realities of programming, development USE in Informatics has little in common. There are some basic points, but even if you understand tasks a little, this does not mean that you will eventually become a good developer. But there are a lot of areas where IT specialists are needed. You will not lose at all if you want to have a stable income above the average. In IT, you get it. Provided, of course, that you have the appropriate skills. And you can develop and grow here as much as you like, because the market is so huge that you can’t even imagine! And it is not limited only to our state. Work for any company from anywhere in the world! This is all very inspiring, so let the preparation for the exam in computer science be the first small step, after which years of self-development and improvement in this area will follow.

Structure

Part 1 contains 23 short answer tasks. This part contains tasks with a short answer, implying an independent formulation of a sequence of characters. Tasks check the material of all thematic blocks. 12 tasks belong to the basic level, 10 tasks to an increased level of complexity, 1 task to a high level of complexity.

Part 2 contains 4 tasks, the first of which is of an increased level of complexity, the remaining 3 tasks are of a high level of complexity. The tasks of this part involve writing a detailed answer in an arbitrary form.

3 hours 55 minutes (235 minutes) are allotted to complete the examination paper. It is recommended to take 1.5 hours (90 minutes) to complete the tasks of part 1. The rest of the time is recommended to be devoted to the tasks of part 2.

Explanations for grading assignments

The performance of each task of part 1 is estimated at 1 point. The task of part 1 is considered completed if the examiner gave the answer corresponding to the code of the correct answer. Completion of the tasks of part 2 is estimated from 0 to 4 points. The answers to the tasks of part 2 are checked and evaluated by experts. The maximum number of points that can be obtained for completing the tasks of part 2 is 12.

For effective training in computer science for each task, a brief theoretical material is given to complete the task. More than 10 training tasks with analysis and answers were selected, developed on the basis of the demo version of previous years.

There are no changes in KIM USE 2020 in informatics and ICT.

The areas in which the knowledge test will be carried out:

Programming;
Algorithmization;
ICT tools;
Information activity;
Information processes.

Necessary actions when preparing:

Repetition of the theoretical course;
Solution tests in informatics online;
Knowledge of programming languages;
Pull up mathematics and mathematical logic;
Use a wider range of literature - the school curriculum for success in the exam is not enough.

Exam Structure

The duration of the exam is 3 hours 55 minutes (255 minutes), of which one and a half hours are recommended to be devoted to completing the tasks of the first part of the KIMs.

Tasks in tickets are divided into blocks:

Part 1- 23 tasks with a short answer.
Part 2- 4 tasks with a detailed answer.

Of the proposed 23 tasks of the first part of the examination paper, 12 belong to the basic level of knowledge testing, 10 - to increased complexity, 1 - to a high level of complexity. Three tasks of the second part of a high level of complexity, one - an increased one.

When solving, it is obligatory to record a detailed answer (arbitrary form).
In some tasks, the text of the condition is submitted immediately in five programming languages - for the convenience of students.

Points for tasks in computer science

1 point - for 1-23 tasks
2 points - 25.
3 points - 24, 26.
4 points - 27.
Total: 35 points.

To enter a technical university of an intermediate level, you must score at least 62 points. To enter the metropolitan university, the number of points must correspond to 85-95.

To successfully write an examination paper, you need a clear command of theory and constant practice in solving tasks.

Your formula for success

Work + work on mistakes + carefully read the question from beginning to end to avoid mistakes = maximum score on the exam in computer science.

For tasks 1-18, choose only one correct answer.

For tasks 1-8, choose only one correct answer.

The total number of participants in the main period of the exam this year is more than 67 thousand people. This number has increased significantly compared to 2017, when 52.8 thousand people took the exam, and compared to 2016 (49.3 thousand people ), which corresponds to the trend towards the development of the digital sector of the economy in the country.

In 2018, compared to 2017, the share of unprepared exam participants slightly increased (by 1.54%) (up to 40 test points). The share of participants with a basic level of training decreased by 2.9% (range from 40 to 60 tb). The 61-80tb group of test takers increased by 3.71%, partly due to a 2.57% decrease in the share of the 81-100tb test takers. Thus, the total share of participants who scored significant points for competitive admission to higher education institutions (61-100 t.b.) increased by 1.05%, despite a decrease in the average test score from 59.2 in 2017 to 58 4 in the current year. Some increase in the proportion of participants who scored high (81-100) test scores is partly due to improved preparation of exam participants, partly to the stability of the examination model
