Audio

This section provides you with information on the 9th grade exam "Informatics" in the OGE format. Demo versions, theory guides, exam specifications and practice tests are available. You can find information about the exam format below.

Exam Information

The computer science exam consists of two parts and 20 tasks.

First part contains 18 tasks of basic and advanced difficulty levels

6 tasks with selection and recording of the answer in the form of one digit
12 tasks, implying that the examinee independently formulates and writes down the answer in the form of a sequence of characters

Second part contains 2 tasks of high difficulty level.

The tasks of the second part involve practical work by students on a computer using special software. The result of each task is a separate file. Task 20 is given in two versions: 20.1 and 20.2; The examinee must choose one of the options for the task.

Among tasks 1–6, tasks from all thematic blocks are presented, except for tasks on the topic “Organization of the information environment, information search”; among tasks 7–18 there are tasks on all topics except the topic “Design and Modeling”.

The tasks in Part 2 are aimed at testing practical skills in working with information in text and tabular forms, as well as the ability to implement a complex algorithm. In this case, task 20 is given in two versions: task 20.1 involves developing an algorithm for a formal executor, task 20.2 is to develop and write an algorithm in a programming language. The examinee independently chooses one of two options for the task, depending on whether he has studied any programming language.

Distribution of tasks by parts of the examination paper

OGE in computer science is one of the exams that is taken at the student’s choice. To enter the 10th grade after the 9th grade, you need to choose 2 subjects of your choice and 2 disciplines are mandatory. Computer science is chosen by those who enter a class with a certain specialization or plan to enter a college or technical school where this subject is needed. Also, many people choose computer science because it seems like the easiest option. If you know a computer and have not chosen a subject to take, computer science is worth paying attention to.

The exam is divided into two parts - written and practical, which is performed on a computer.

The first part includes 18 tasks (the number may change every year), the difficulty level is basic. The goal is to test students’ theoretical knowledge for compliance with the norms and standards of the program. Main topics and focus of assignments: converting numbers from one number system to another, converting units of measurement, theoretical knowledge on all topics of the course. If you learn how to perform such tasks, remember the features and solution algorithm, there will be no problems in the exam. Also in this part there are programming tasks - this does not require specific knowledge and special abilities, it is enough to learn the algorithm.
The second part requires you to complete two tasks on the computer. Moreover, you need to cope without the help of the Internet. The tasks are aimed at testing work, for example, in an Office suite or programming environment. The first task, most often, is on Excel skills: find the sum, use formulas and graphs to demonstrate any values. Programming is performed in the Kumir, Python, Pascal environment. The student receives a task and completes it - the result should be a working, simple algorithm.

It is quite possible to complete the course and prepare for the exam with basic skills. The main thing is to practice writing algorithms, study theory, and learn how to perform tests. The online resource “I will solve the OGE in computer science” will help with the latter - it contains many tasks of different difficulty levels, after completing which the student can easily pass the exam with a high score.
It is recommended that you begin your preparation by familiarizing yourself with , which outlines all the topics worth paying attention to. This will help create a schedule and preparation plan. Clearly set goals and an action plan, a little self-discipline and you can master the material even in six months. To master programming, you can use the help of a teacher, study textbooks on your own, study with a tutor - it’s a matter of choice.
Programming is considered the most difficult topic - spend more time on it. But classes using a special website resource will allow you to gain experience solving tasks of varying complexity online. Only by knowing how to use the information you have learned can you pass the OGE in computer science with a high score.

There are no changes in the structure and content of the 2019 examination paper compared to 2018.

In this section you will find online tests that will help you prepare to take the OGE (GIA) in computer science. We wish you success!

The standard OGE test (GIA-9) of the 2019 format in computer science and ICT contains two parts. The first part contains 18 tasks with a short answer, the second part contains 2 tasks that must be completed on the computer. In this regard, only the first part (the first 18 tasks) is presented in this test. According to the current exam structure, among these 18 questions, only the first 6 questions offer answer options. However, for the convenience of passing tests, the site administration decided to offer answer options for each task. However, for tasks in which the compilers of real test and measurement materials (CMMs) do not provide answer options, we decided to significantly increase the number of these answer options in order to bring our test as close as possible to what you will have to face at the end of the school year.

Maximum score

Performer Robot can navigate through a labyrinth drawn on a plane divided into cells. Between adjacent (on the sides) cells there may be a wall through which the Robot cannot pass. Robot has nine commands. Four commands are order commands:

up down left right

When any of these commands is executed, the Robot moves one cell accordingly: up down ↓ , left ← , right → . If the Robot receives a command to move through a wall, it will collapse. Robot also has a team paint over , in which the cell in which the Robot is currently located is painted over.

Four more commands are condition checking commands. These commands check if the path is clear for the Robot in each of four possible directions:

top free bottom free left free right free

These commands can be used in conjunction with a condition"If" , having the following form:

if condition then

sequence of commands

All

Here's the condition - one of the commands for checking a condition.Command Sequence- this is one or more any commands-orders. For example, to move one cell to the right, if there is no wall on the right, and paint the cell, you can use the following algorithm:

if the right is free then

right

paint over

All

In one condition, you can use several condition checking commands using logical connectives and, or, not, for example:

if (right is free) and (not below is free) then

right

All

You can use a loop to repeat a sequence of commands"Bye" , having the following form:

no condition yet

sequence of commands

kts

For example, to move to the right while it is possible, you can use the following algorithm:

nts the right is free for now

right

kts

Complete the task.

The endless field has horizontal and vertical walls. The right end of the horizontal wall is connected to the bottom end of the vertical wall. The lengths of the walls are unknown. Each wall has exactly one passage, the exact location of the passage and its width are unknown. The robot is in a cage located directly to the right of the vertical wall at its upper end. The figure shows one of the possible ways to position the walls and the Robot (the Robot is designated by the letter “P”).

Write an algorithm for the Robot that paints all the cells located directly above the horizontal wall and to the left of the vertical wall. The passages must remain unpainted. The robot must paint only cells that satisfy this condition. For example, for the picture above, the Robot must color in the following cells (see picture).

When executing the algorithm, the Robot must not be destroyed; the execution of the algorithm must be completed. The final location of the Robot can be arbitrary. The algorithm must solve the problem for any feasible arrangement of walls and any location and size of passages inside the walls. The algorithm can be executed in a formal executor environment or written in a text editor. Save the algorithm in a text file.

20.2 Write a program that, in a sequence of natural numbers, determines the sum of numbers that are multiples of 3. The program receives as input the number of numbers in the sequence, and then the numbers themselves. The sequence always contains a number that is a multiple of 3. The number of numbers does not exceed 100. The entered numbers do not exceed 300. The program must output one number - the sum of numbers that are multiples of 3.

Example of the program:

Input data	Output
3 12 25 9

State process final certification involves the use of standardized tests to monitor the quality of students’ preparation and, in general, the entire educational process in secondary school.

To successfully pass the OGE in computer science 2019, preparation must begin at the beginning of the academic year, taking into account the innovations being adopted.

Structure of the 2019 OGE in computer science

The proposed set of tests is divided into 2 group categories:

Part 1 of the examination paper contains 18 tasks - 11 at a basic level of difficulty and 7 at an increased level of difficulty. The first six tasks with one correct answer out of four options (these are tasks of category A) and twelve tasks where the answer can be either a word, a number or an entire digital sequence (these are tasks of category B).
Part 2 contains 2 tasks of a high level of complexity - the graduate is offered two tests. But everyone needs the most detailed and detailed answer. Most likely, you will need a rather complex solution. In task numbers 19 and 20, you will need to write a program for two proposed tasks (these are tasks of category C).

After completing the tasks of Part 1, the examinee submits a form for recording answers and proceeds to completing the tasks of Part 2.

The duration of the exam is 150 minutes. Test developers recommend completing tasks in categories A and B in 75 minutes, freeing up the remaining time for writing a programming task (category C).

Practical part

Previously, the student selects software and hardware and the appropriate language to complete the second part of the OGE.In accordance with the specified parameters, he is provided with a workplace equipped with a computer.To complete task 19, you will need a spreadsheet program. To complete task 20.1, it is recommended to use the performer’s learning environment “Robot”; the second version of task (20.2) involves writing the algorithm in the programming language being studied.

Options for acceptable languages for writing a program:

Algorithmic language
BASIC
Pascal
C++
Python

Each task of the practical part is completed in a separate file prepared in the appropriate program (text editor or spreadsheet). Exam participants save these files in a directory under names specified by the exam organizers (technician).

The answer forms (after completing the work on the computer) contain the names of the files with completed tasks, including a unique number (CMM number).

An excellent opportunity to practice the examination process, study possible types of tasks, and even repeat the curriculum - demo version of the OGE in computer science and ICT 2019.

Additional information about the OGE 2019

When performing the first and second categories of tasks, the use of technical devices is not allowed: calculators, computer equipment, mobile phones. Reference books and books on computer science are also prohibited.

When starting practical part 2 (category C), the student receives a personal computer.

As for success indicators, to be rated “satisfactory”, a participant in the OGE only needs to score 5 points. The maximum number for correctly solving all 20 OGE questions is 22 points.

Psychological secrets of successful exam preparation

Taking the exam

“Fortune always smiles on those who have worked hard,” says an English proverb. I would like to add: “and to those who know how to show the results of their work.” In an exam, that's exactly what you do - demonstrate what you've learned. So do it calmly and confidently. Try to change your idea of the exam - it’s not torture, not execution, but simply a test of your knowledge, especially since you know everything (or almost everything).

On the day of the exam

1. Pre-exam stress is often accompanied by a lack of appetite. But even if “a piece doesn’t fit into your throat,” you definitely need to eat at least a little. Otherwise, in a state of stress, a sharp decrease in blood sugar levels may occur and accompanying symptoms may occur - trembling, sweating, weakness, dizziness, headache, nausea... It won’t take long for you to faint.

2. You should not go to the exam with a full stomach. Breakfast should be light, containing foods rich in protein and carbohydrates. In the morning before the exam, it is best to eat yogurt, as well as cottage cheese, scrambled eggs, milk porridge or muesli, a sandwich with cheese or honey and drink tea with lemon and sugar. You shouldn’t “pick yourself up” with strong coffee. If your nerves are on edge, but you realize that your body needs food, eat 1 tsp. honey, 2 walnuts, 3 pieces of dried apricots and drink a glass of biokefir. 1-2 bananas, a handful of raisins and a fruit milkshake will also help maintain your strength.

3. Music is an extremely effective way to relieve pre-exam stress. . When getting ready for the exam, turn on recordings of a bravura march, czardas or energetic guitar flamenco, and you will be convinced that your fear and inner trembling will disappear. If you love classical music, Bach's preludes and fugues for organ, Tchaikovsky's Fifth Symphony, and all the orchestral works of Alexander Scriabin will help you. Bach's music, by the way, is very effective if intense intellectual work is to be done. Compositions by Bryan Adams, Tina Turner, Bon Jovi and Riccardo Foglia also set the mood for battle.

4. But what you should never do is take sedatives. The result could be disastrous. Lethargy and lethargy will not allow you to concentrate!
Before leaving the house, apply a few drops of lavender, basil or mint essential oil, which has calming properties, to your temples or wrists. You can also drop this oil on a handkerchief and then periodically inhale its aroma during the exam.

Techniques for dealing with fear

1 . Stop being afraid! Many people are well aware of the state of panic before exams: “I don’t know anything! I don’t remember anything!” Try to direct your thoughts in a different direction: “I worked long and purposefully, I did everything in my power, I still know something from all the material and quite well.”

2. Do breathing exercises. This is the fastest, easiest and most effective way to overcome feelings of stress and panic. Close your eyes and breathe slowly and deeply. Exhalation should be 2-3 times longer than inhalation. As you inhale, imagine that you are sniffing your favorite scent through your nose. Exhale through slightly closed lips as if you want to blow out a candle flame or blow on a spoon of hot soup. 3-5 minutes after the start of breathing exercises, you can add self-hypnosis formulas to them:« I relax and calm down", synchronizing them with the rhythm of your breathing. At the same time, the words “ I" And " And"should be pronounced in inhale, and the words “ relaxing" And " I'm calming down" - on exhale.
You can also say to yourself:

“I am calm and confident”

“My memory works well. I remember evrything"

“I can prove that I worked hard and learned everything.”

Autotraining is an effective technique: the brain perfectly obeys such commands.

3. Learn to never think about failing an exam.. On the contrary, you need to mentally paint yourself a picture of a confident, clear answer, complete victory. We get what we think hard about, literally programming ourselves for the final result. And for this result to satisfy us, we need to think about the good, setting ourselves up for success: “I will succeed, at the right moment I will remember everything.”

4. Don't get caught up in other people's anxiety. As a rule, in front of the door of the auditorium in which the exam is taking place, there is a crowd of students shaking with fear, discussing how strict and picky this or that examiner is and from time to time saying: “Oh, I’m definitely going to fail today! Everything flew out of my head! I’m already shaking all over!” Do not crowd together with them so as not to be “infected” by their fear. Experience your anxiety alone, step aside, wander along the corridor, look out the window.

5. Relieve tension. The simplest movements will help you get rid of painful discomfort. Make a few circular movements with your head, stretch your arms, and shrug your shoulders. If possible, box, throwing punches into an empty space and imagining that you are punching your fear.

In a stressful situation, it is useful to yawn. By yawning sweetly three to five times, you will not only reduce anxiety, but also activate your brain. To trigger the yawn reflex, you need to use your middle fingers to massage the muscles between your ear and cheek.

6. Do self-massage. A light massage of the occipital area of the head distracts from obsessive fear and also helps to significantly increase intelligence. Massaging the tips of the little fingers, as well as performing yoga for the fingers, the so-called mudras, helps relieve emotional stress. This word refers to the joining of fingers in a certain combination.
Thus, the mudra of the Earth helps with stress, deterioration of psychophysical condition, increases self-esteem and self-confidence. To perform this, press the ring and thumb fingers of both hands tightly against each other with the pads, straighten the remaining fingers and spread them slightly apart. It is useful to do this gesture as often as possible and keep your fingers in this position for as long as possible.
If you are feeling very stressed, place your left hand on the table, palm down. With your right hand, for 3-5 minutes, in a clockwise circular motion, massage the point of intersection of the conventional lines of the thumb and index finger, while keeping the thumb as far as possible from the index finger. Then change your hand, but now make movements counterclockwise.
