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

A high school student's knowledge of mathematics is definitely not zero. In the Russian language - even more so.

But with computer science the situation is much more complicated. What is studied in school in the classroom has nothing to do with the preparation program for the Unified State Exam in computer science.

What is the Unified State Exam in computer science?

The Unified State Exam test in computer science contains 27 tasks that relate to a variety of topics. These are number systems, Boolean algebra, algorithmics, programming, modeling, elements of graph theory.

The Unified State Examination in computer science covers a very wide range of information. Of course, the exam will only require 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 take any of these topics at school. This is usually true!

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

And therefore, almost none of the students solve the famous problem on systems of logical equations. This problem in the Unified State Examination in computer science 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 problem 23 from the Unified State Exam in computer science cannot be solved at all? Of course not! Our students solve it regularly every year. In our preparation course for the Unified State Exam in computer science, from many topics we take only what is required for the exam. And we pay maximum attention to these tasks.

Why doesn’t the school prepare for the Unified State 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 or programs. Therefore, teachers in computer science lessons give schoolchildren completely different material - who can do what. Moreover, some schools do not have computer science lessons at all.

What do high school students usually do during computer science classes? Are they really playing shooting games?

Fortunately, in computer science classes at school, students do not do nonsense, but quite useful things. For example, they study Word and Escel. This will be useful in life, but, unfortunately, for passing the Unified State Exam it is absolutely useless.

Moreover, the guys study Word at a serious level, and some even pass exams in computer layout and receive a layout designer’s certificate. Some schools teach 3D modeling. Many schools offer web design. This is a wonderful topic that will be useful in the future, but it has nothing to do with the Unified State Exam! And by coming to our courses, a student really prepares for the Unified State Exam in computer science from scratch.

The situation is similar for high school students at specialized lyceums. Strong specialized lyceums honestly teach programming in computer science lessons. The guys come out of there as good programmers. But in the Unified State Exam in computer science, only 5 tasks are at least somehow related to programming, and of these, exactly one task in the Unified State Exam version is devoted to writing a program! The result is a maximum of 6 problems on the Unified State Exam in computer science.

How long does it take to prepare for the Unified State Exam in computer science from scratch?

There is good news! You can prepare for the Unified State Exam in computer science from scratch in one year. It is not easy, but it is possible, and our students prove it every year. The preparation course for the Unified State Exam in computer science is not very large. 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 11th grade, it is hardly possible to fully master programming in a year. Therefore, task No. 27 of the Unified State Examination in computer science will remain unsolved. She is the most difficult.

It is especially difficult to prepare for the Unified State Exam in computer science from scratch for those students who have never been familiar with programming and do not know what it is. This area is quite specific, so training in programming requires spending a lot of time and solving a huge number of problems.

In our courses, we make sure to cover all typical programming tasks. And not once during the exam did a programming task turn out to be a surprise for our students - they were all covered in the courses. And only problem 27 remains overboard for those who did not do programming at all until the 11th grade.

When students and parents come to our computer science courses, they are sometimes surprised to not see computers in the classroom. They think that since they came to prepare for the Unified State Exam in computer science, there should be computers on the tables. But they are not there! How necessary is it to have laptops and computers when preparing for the Unified State Exam in computer science?

This is a feature of the Unified State Examination in computer science. There will be no computer during the exam! And yes, you will have to solve tasks with a pen on a piece of paper, because this is the format in which the Unified State Examination in computer science is currently being held. This is a real problem for those who take it.

Even high school students from specialized lyceums who are good at programming may find themselves helpless on the Unified State 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 “Hard to study, easy to fight.”

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 this in 2017, but did not do it. Will they do it in 2018? We don't know yet. If they introduce this exam format, preparing for the Unified State Exam in computer science from scratch will be much easier.

So, a year of active preparation for the Unified State Exam in computer science from scratch, and your result is 26 problems 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 theoretical material and my book for preparation "Informatics. Author's course of preparation for the Unified State Exam", where practice in solving problems is given.

Which programming language to choose, which tasks to focus on and how to allocate time during the exam

Teaches computer science at Foxford

Different universities require different entrance exams for IT areas. Somewhere you need to take physics, somewhere you need to take computer science. It’s up to you to decide which exam to prepare for, but it’s worth keeping in mind that the competition for specialties where you need to take physics is usually lower than for specialties where the Unified State Exam in computer science is required, i.e. the likelihood of enrolling “through physics” is greater.

Why then take the Unified State Exam in computer science?

  • It is faster and easier to prepare for it than for physics.
  • You will be able to choose from more specialties.
  • It will be easier for you to study in your chosen specialty.

What you need to know about the Unified State Exam in computer science

The Unified State Examination in computer science consists of two parts. The first part contains 23 problems with a short answer, the second - 4 problems with a detailed answer. The first part of the exam contains 12 basic level tasks, 10 advanced level tasks and 1 high level task. In the second part there is 1 task of an advanced level and 3 tasks of a high level.

Solving the problems from the first part allows you to score 23 primary points - one point for each completed task. Solving the problems of the second part adds 12 primary points (3, 2, 3 and 4 points for each problem, respectively). Thus, the maximum primary points that can be obtained for solving all tasks is 35.

Primary scores are converted into test scores, which are the result of the Unified State Examination. 35 raw points = 100 test points for the exam. At the same time, more test points are awarded for solving problems from the second part of the exam than for answering problems in the first part. Each primary score received for the second part of the Unified State Examination will give you 3 or 4 test points, which in total is about 40 final points for the exam.

This means that when completing the Unified State Exam in computer science, it is necessary to pay special attention to solving problems with a detailed answer: No. 24, 25, 26 and 27. Their successful completion will allow you to score more final points. But the cost of a mistake during their implementation is higher - the loss of each initial point is fraught with the fact that you will not pass the competition, because 3-4 final points for the Unified State Exam with high competition in IT specialties can become decisive.

How to prepare to solve problems from the first part

  • Pay special attention to tasks No. 9, 10, 11, 12, 15, 18, 20, 23. These tasks, according to the analysis of the results of past years, are especially difficult. Difficulties in solving these problems are experienced not only by those who have a low overall score for the Unified State Exam in computer science, but also by “good” and “excellent” students.
  • Memorize the table of powers of the number 2.
  • Remember that KBytes in tasks means kibibytes, not kilobytes. 1 kibibyte = 1024 bytes. This will help avoid errors in calculations.
  • Carefully study the Unified State Exam options of previous years. The computer science exam is one of the most stable, which means that you can safely use the Unified State Exam options from the last 3-4 years for preparation.
  • Get to know different options for wording assignments. Remember that minor changes in wording will always lead to poorer exam results.
  • Read the task conditions carefully. Most errors when completing tasks are due to an incorrect understanding of the condition.
  • Learn to independently check completed assignments and find errors in answers.

What you need to know about solving long-answer problems

Task 24 - to find an error

Problem 25 requires writing a simple program

Problem 26 - game theory

Task 27 - you need to program a complex program

The main difficulty in the exam is problem 27. It can only be decided60-70% of those writing the Unified State Exam in computer science. Its peculiarity is that it is impossible to prepare for it in advance. Every year a fundamentally new task is presented for the exam. When solving problem No. 27, not a single semantic error can be made.

How to calculate time in an exam

Refer to the data given in the specification of control measuring materials for the Unified State Exam in computer science. It indicates the approximate time allotted for completing the tasks of the first and second parts of the exam.

The Unified State Examination in computer science lasts 235 minutes.

Of these, 90 minutes are allocated to solving problems from the first part. On average, each task from the first part takes from 3 to 5 minutes. It takes 10 minutes to solve problem No. 23.

There are 145 minutes left to solve the tasks of the second part of the exam, while solving the last problem No. 27 will require at least 55 minutes. These calculations were carried out by specialists from the Federal Institute of Pedagogical Measurements and are based on the results of previous years' exams, so they should be taken seriously and used as a guide for the exam.

Programming languages ​​- which one to choose

  1. BASIC. This is an outdated language, and although it is still taught in schools, there is no point in wasting time on mastering it.
  2. School algorithmic programming language. It is designed specifically for early learning of programming, convenient for mastering initial algorithms, but contains virtually no depth, and there is no room for development.
  3. Pascal. It is still one of the most common programming languages ​​for teaching in schools and universities, but its capabilities are also very limited. Pascal is quite suitable as a language for writing the Unified State Exam.
  4. C++. A universal language, one of the fastest programming languages. It is difficult to learn, but in practical application its possibilities are very wide.
  5. Python. It is easy to learn at a beginner level; the only thing required is knowledge of the English language. At the same time, with in-depth study, Python provides the programmer with no less opportunities than C++. Having started studying Python in school, you will continue to use it in the future; you will not have to relearn another language in order to achieve new horizons in programming. To pass the Unified State Exam, it is enough to know Python at a basic level.

Good to know

  • Computer science papers are assessed by two experts. If the experts' assessment results differ by 1 point, the higher of the two points is assigned. If the discrepancy is 2 points or more, the work is rechecked by a third expert.
  • A useful site for preparing for the Unified State Exam in computer science -

It is simply impossible to enroll on a budget at a prestigious university for popular majors such as economics, law, computer security, etc. Most people are simply not able to pay tuition fees - only a few can pay over 100 thousand rubles a year.

At the same time, the school curriculum, in most cases, does not include the topics included in the Unified State Examination. And most school teachers are not able to give the student the level that is necessary to get high scores. You can often hear from students about rewriting textbooks instead of competent teaching, solving in lessons the wrong examples that they need, and a small number of lessons they need.

What should students and parents do in this case? Most parents try to find their child a professional teacher in the required subject, which, in principle, is correct, especially if you take subjects such as mathematics and physics. Preparation for these subjects is extremely difficult: to pass mathematics you need to solve a huge number of different variants of tasks, in physics you need to know all the necessary laws, formulas, and be able to apply them.

The principle of passing an exam in computer science is fundamentally different from passing the subjects mentioned above. Firstly, most of the tasks are standard, and in order to complete them, you do not need to solve hundreds of different options. Secondly, some of the tasks are designed for the ability to think logically. Many students, having taken a trial course in computer science for the first time, are sincerely surprised that the tasks are like puzzles, and begin solving them in their free time just for fun.

Here you need to understand that some tasks are extremely difficult and will require maximum effort from the student not only to solve them, but even to understand what they actually want from him. However, to get a passing score (40 points in 2013), you just need to pore over the assignments for a few hours. And this is with almost zero knowledge base on the subject.

Unified State Examination tasks in computer science can be divided into several main blocks:

  1. Programming. Traditionally the most difficult section of the exam. The problem is that in most secondary schools, teachers teach a minimum level of programming, or even avoid this topic altogether. And the student simply cannot understand the basic principles of the program. However, on the modern Internet there is a huge amount of reference materials written in a language that students can understand. And yet, to study this topic, it is highly advisable to hire a tutor, at least to gain basic knowledge.
  2. Logics. The second most difficult section of the exam. To complete most tasks, you need to solve a logical equation or system and be able to work with sets.
  3. Amount of information. What could be easier than counting the number of bytes in a text document? Given that the number of characters in this document and the size of each character are given.
  4. Spreadsheets. Here you need to know the basic mathematical functions of the MS EXCEL program and the principle of addressing cells in a table. Most people have Excel installed with Microsoft Office, and completing assignments at home is easy.
  5. Working with number systems. Here you will need to remember elementary school: the ability to divide with a remainder and solve examples in a column, because It is prohibited to use a calculator on the Unified State Examination.
  6. Various tasks for thinking, logic, counting.

Of course, with the proper desire, it is quite possible to prepare for the Unified State Exam on your own and score 60-80 points, but it is highly advisable to find a tutor, or, in extreme cases, just a person knowledgeable in computer science who can point out mistakes and suggest the right solution. It is enough to come to such a person once a week or two with assigned tasks in which problems have arisen. And, of course, actively use the Internet - on programming forums, on social networks, on thematic sites, a huge number of all kinds of tasks with detailed solutions.
