Everything you need to know about the exam in computer science. Everything you need to know about the exam in informatics Exam threshold informatics

The author of the article is a professional tutor Lada Borisovna Esakova.

The exam in computer science is behind. My students passed the exam well: 79, 81, 88 points. This is a decent result. At the same time, the strongest could qualify for 90-100. So what's the deal? Where are the missing points "lost"?

Here is a pattern: all these students completed ALL tasks with a detailed answer (part C) for the highest or almost the highest score. That is, the highest score for the entire C-part and the loss of 20 or more points on nonsense problems. The situation repeats itself from year to year, and therefore I do not consider it accidental. This situation is typical for the Unified State Exam in Informatics.

The structure of the exam in informatics

Let's look at the structure of the exam paper in computer science. There are 27 tasks in total. Of these, 23 with a short answer (former part B) and 4 with a detailed answer (former part C).

In the examination paper there are tasks that require a good knowledge of mathematics, logic, the ability to analyze and think abstractly. There are also problems based on accurate, monotonous execution of an algorithm or enumeration of options. That is, the student is given the opportunity to work like a computer.

Tasks with a short answer are estimated at 1 point, tasks with a detailed answer - at 3, 2, 3 and 4 points. Thus, for the first part, you can get a maximum of 23 points, and for the second 12.
See how heavy the first part is?

The specification of the Unified State Examination in Informatics and ICT indicates the recommended time for completing each task.

It is recommended to spend an hour and a half on the first part of the exam in computer science (including checking and rewriting on the form). The second part is 2.5 hours. This is a very correct recommendation. If you plan to do the whole second part, you cannot spend more than an hour on solving the first part. Another half hour will be spent on checking and rewriting!

But what is an hour for 23 tasks? That's right, it's less than 3 minutes each! I think that the tasks of the first part are quite simple for most of the students, but they often require careful sorting and analysis of a large amount of data. Even in the case of an excellent understanding of the subject, the requirements are almost impossible to fulfill! With a full understanding of the progress of solving the problem, there is simply not enough time.

And what does it mean that it is impossible to solve the entire part 1 on the exam in computer science quickly and without errors, while leaving a sufficient resource of time for the complex tasks of part 2?

Of course it is possible. The experience of preparing athletes for competitions will help us. I often tell my students: “If you know well how to score a goal from any position, have watched many matches and know by heart all the recommendations of the best coaches, this does not mean that you can be sent to the championship”!

Understanding is not enough here. Practice, error-free actions, almost automatism in solving a specific type of problem are important. And such a practice, as you know, can be obtained only by a large number of repetitions of the same, monotonous actions.

So, there is a recipe for achieving the desired time characteristics. I have enough teaching materials, collections of all types of problems. Let's get down to business. And here is the key point ...

Accurate and creative people. Which of them is easier to pass the exam in computer science?

Recall that people in terms of perception of information, thought process, method of constructing cause-and-effect relationships can be attributed to different types: introverts - extroverts, rationalists - irrational, sensorics - intuitions, etc. I will not go into the territory of psychologists, I will just note in general that strong students applying for 90-100 points on the Unified State Exam in computer science, according to the way of thinking, are of two polarly different types: Accurate and Creative.

Accurate: Painstaking, executive, diligent.
Creative: Fast, original, thinking outside the box.

Accurate people have good handwriting, rarely make computational mistakes, enjoy perfectly executed and designed work, even from routine work. They are excellent at handling complex tasks based on gradual conclusions, calculations and evidence. However, they are perplexed by a task of an unknown type.

Creatives - write quickly and illegibly, have developed abstract thinking, a wide range of knowledge in various fields, the ability to find beautiful and unexpected solutions to the most unusual problems. However, they categorically do not accept routine monotonous work. It is difficult and boring for them to force themselves to perform understandable actions.

In life, these types are not so pronounced. A student can have both qualities.
What happens on the computer science exam?

Those students who faultlessly complete complex tasks of the second part of the Unified State Exam in computer science (especially task 27) are closer to Creatives. That is why it is very difficult to get them to do a large homework, consisting of simple, similar, but very voluminous tasks. They are annoyed by the need to spend time repeating the same understandable actions many times.

When asked about doing homework, strong students usually answer: "I did the first 3 tasks, the rest are exactly the same, and it is so clear how to do them." That is, I learned the technique of scoring a goal instead of running around the stadium for hours.

As a result, after the exam, I again hear the same phrase: "The tasks were very simple, I just didn't have enough time."

The conclusion is obvious. It is necessary to realize that the Unified State Exam in computer science differs from the Unified State Exam in other technical disciplines by the presence of voluminous, uncreative, monotonous tasks that require accuracy and speed of implementation. Therefore, in preparation, along with learning new material, solving complex interesting problems, you need to "run around the stadium" more, gaining the necessary automatic skills.

And then your brilliant goal, your 100 points for the Unified State Exam in Computer Science become a very real goal.

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

Teaches computer science at Foxford

Different universities require different IT entrance exams. Somewhere you need to pass physics, somewhere - computer science. Which exam to prepare for is up to you, but it should be borne in mind that the competition for the specialty where you need to pass physics is usually lower than for the specialties where the Unified State Exam in Informatics is required, i.e. the likelihood of entering "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 the chosen specialty.

What you need to know about the exam in computer science

The Unified State Exam in Informatics consists of two parts. In the first part there are 23 problems with a short answer, in the second - 4 problems with a detailed answer. The first part of the exam contains 12 basic-level assignments, 10 advanced-level assignments and 1 high-level assignment. In the second part - 1 task of an advanced level and 3 - a high one.

Solving problems from the first part allows you to score 23 primary points - one point for the 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 to test scores, which are the result of the exam. 35 primary points = 100 test points for the exam. In this case, more test points are awarded for solving problems from the second part of the exam than for answering the problems of the first part. Each primary score earned in the second part of the exam will give you 3 or 4 test points, which adds up to about 40 final exam points.

This means that when completing the Unified State Exam in Informatics, 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 gain more final points. But the cost of an error during their implementation is higher - the loss of each primary 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 for Part One Challenges

  • Pay special attention to the tasks number 9, 10, 11, 12, 15, 18, 20, 23. These tasks, according to the analysis of the results of the past years, are especially difficult. Difficulties with the solution of these problems are experienced not only by those who have a low overall score for the Unified State Exam in computer science, but also "good" and "excellent" students.
  • Memorize the table of powers of number 2.
  • Remember that Kbytes in tasks means Kibybytes, not Kilobytes. 1 kibyte = 1024 bytes. This will help avoid calculation errors.
  • Carefully study the options for the USE from previous years. The computer science exam is one of the most stable, which means that you can safely use the USE options for the last 3-4 years for preparation.
  • Get to know the different options for the wording of the tasks. Remember that minor wording changes will always result in poor exam scores.
  • Read the problem statement carefully. Most of the errors in completing assignments are associated with a misunderstanding of the condition.
  • Learn to independently check the completed tasks and find errors in the answers.

What you need to know about solving problems with a detailed answer

24 task - to find an error

25 task requires drawing up a simple program

Problem 26 - on game theory

27 task - it is necessary to program a complex program

The main difficulty in the exam is 27 problems. It can only be solved60-70% of those writing the exam in computer science. Its peculiarity lies in the fact that it is impossible to prepare for it in advance. Every year a fundamentally new problem is presented for the exam. When solving problem # 27, not a single semantic error should be allowed.

How to time your exam

Focus on the data that are given in the specification of control measuring materials for the exam in informatics. It indicates the approximate time allotted for completing the tasks of the first and second parts of the exam.

The exam in computer science lasts 235 minutes

Of these, 90 minutes are devoted to solving problems from the first part. On average, each task from the first part takes 3 to 5 minutes. It takes 10 minutes to solve problem 23.

There are 145 minutes left to solve the tasks of the second part of the exam, while solving the last problem # 27 will take at least 55 minutes. These calculations were carried out by specialists from the Federal Institute for Pedagogical Measurements and are based on the results of past exams, so they should be taken seriously and used as a guide for the exam.

Programming languages ​​- which one to choose

  1. BASIC. It is an outdated language, and although it is still being taught in schools, there is no point in wasting time mastering it.
  2. School algorithmic programming language. It is designed specifically for early learning in programming, convenient for mastering the initial algorithms, but practically does not contain depth, there is nowhere to develop in it.
  3. Pascal. It is still one of the most common programming languages ​​for teaching in schools and universities, but its capabilities are severely limited. Pascal is quite suitable as a writing language for the exam.
  4. C ++. A universal language, one of the fastest programming languages. It is difficult to learn from it, but in practical application its possibilities are very wide.
  5. Python... It is easy to learn at an elementary level, the only thing that is required is knowledge of the English language. At the same time, with an in-depth study of Python, it provides the programmer with no less opportunities than C ++. Having started learning "Python" at school, you will use it in the future, you do not have to relearn to another language in order to reach new horizons in programming. To pass the exam, it is enough to know "Python" at a basic level.

Good to know

  • Informatics works are evaluated 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.

Each graduate understands perfectly well that for successful admission to the specialty of interest, it is necessary to qualitatively prepare for the Unified State Exam 2018 and score the maximum possible points. What does it mean to “pass the exam well” and how many points will be enough to compete for a budget place in a particular university? This will be discussed in this article.

We will touch on such important issues:

First of all, it is important to understand that there is:

  • minimum score, giving the right to obtain a certificate;
  • the minimum score that allows you to submit documents to the university;
  • the minimum score sufficient for real admission to the budget for a specific specialty at a certain university in Russia.

Naturally, these figures differ significantly.

Minimum certification score

The minimum attestation points for the USE are set for compulsory subjects - the Russian language and mathematics of the basic level and in 2018 are:

Having overcome this threshold, but not reaching the minimum test score, the examinee will receive a certificate, but will not be able to apply to the university.

Minimum test score

The test minimum is a threshold value that gives the right to enter the university. In other words, persons who have passed the test threshold theoretically have the right to join the struggle for budget places. Although, in practice, it is almost impossible to enter highly ranked universities with minimal indicators.

In 2018, in all subjects, except for the Russian language and basic mathematics, the test minimum USE scores coincide with the certification ones and are:

Item

Minimum test score

Russian language

Mathematics (basic level)

Mathematics (profile level)

Social Studies

Literature

Foreign language

Biology

Computer science

Geography

The principle of calculating the success of the unified state examination assumes that the subject must demonstrate a high, medium or sufficient level of knowledge corresponding to the marks "5", "4" and "3" in the school scale.

In case of an unsatisfactory result, as well as when passing for a point, which the examinee himself considers insufficient for himself, the graduates are given the right to retake the exam.

Minimum score for admission to the budget

Most universities announce the threshold score required for applicants for a budget place. This allows each applicant to realistically assess the prospects for admission and choose universities and specialties, taking into account the points scored on the exam.

In 2018, you can focus on the fact that last season the average passing scores in all USE subjects among applicants who entered MGIMO and other highly regarded universities in the capital fluctuated between the threshold value of 80-90. But, for most of the regional universities of the Russian Federation, a competitive result can be considered already 65-75 points.

Converting the primary score to the resulting score

By completing the tasks offered in the exam ticket, the examinee gains the so-called primary points, the maximum value of which varies depending on the subject. When assessing the level of knowledge, such primary points are converted into resulting ones, which are entered in the certificate and are basic upon admission.

Using an online calculator, you can compare the primary and test scores for subjects of interest.

Just like last year, in 2018 the points scored during the USE affect the score of the certificate and, although the table of comparison of the test score and traditional grades is not officially accepted, you can roughly compare your scores right now using a universal calculator.

Passing points of the top 10 universities in Russia

total

Moscow State University M.V. Lomonosov
Moscow Institute of Physics and Technology
National Research Nuclear University "MEPhI"
Saint Petersburg State University
Moscow State Institute of International Relations
National Research University Higher School of Economics
Moscow State Technical University named after N.E. Bauman
National Research Tomsk Polytechnic University
Novosibirsk National Research State University
Peter the Great St. Petersburg Polytechnic University

Please note that the average passing scores for different specialties at the same university can vary significantly. This figure reflects the minimum score of applicants admitted to the budget, and tends to change every year. The results of 2017 can only serve as a kind of reference point for applicants in 2018, motivating them to achieve the highest possible results.

The minimum passing score is influenced by many factors, including:

  1. the total number of graduates who submitted applications and the points indicated on their certificates;
  2. the number of applicants who provided originals of documents;
  3. the number of beneficiaries.

So, seeing your surname at the 20th place in the list of specialties, which provides for 40 budget places, you can confidently consider yourself a student. But, even if you find yourself on this list of 45, there is no reason to be upset if there are 5-10 people among those standing in front of you who have provided copies of documents, because most likely these people are tuned in to another university and applied for this specialty as a fallback ...
