Dates for passing the OGE in Informatics 2019:
June 4 (Tuesday), June 11 (Tuesday).

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

AT this section you'll find online tests, which will help you prepare for the delivery of the OGE (GIA) in computer science. We wish you success!

The standard OGE test (GIA-9) of the 2019 format in informatics 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 structure of the exam, among these 18 tasks, answers are offered only in the first 6 tasks. However, for the convenience of passing the tests, the site administration decided to offer answers for each task. However, for tasks in which answer options are not provided by the compilers of real control and measuring materials (CMM), 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.

Process of the State final Attestation provides for the use of standardized tests to control the quality of students' preparation and, in general, the entire educational process in secondary school.

For the successful passing of the OGE in Informatics 2019, preparation must begin from the beginning of the academic year, taking into account the innovations being adopted.

Structure of the OGE 2019 in Informatics

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

Part 1 of the examination paper contains 18 tasks - 11 basic level difficulty and 7 advanced difficulty levels. 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 or a number or a whole digital sequence (these are tasks of category B).
Part 2 contains 2 tasks high level complexity - the graduate is offered two test tests. But each needs the most detailed and detailed answer. Most likely, a rather complicated solution will be needed. 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 complete the tasks of part 2.

The duration of the exam is 150 minutes. Test developers advise that category A and B assignments be completed in 75 minutes, freeing up the remaining time to write a programming assignment (category C).

Practical part

Previously, the student selects the 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.Task 19 requires a spreadsheet program. To complete task 20.1, it is recommended to use the learning environment of the executor "Robot", the second version of the task (20.2) provides for writing the algorithm in the programming language being studied.

Variants of allowed languages for writing a program:

Algorithmic language
Basic
Pascal
C++
Python

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

In the answer forms (after completing the work on the computer), the names of the files with completed tasks are entered, including a unique number (KIM number).

A great opportunity to work out the examination process, study possible types of tasks, and repeat the curriculum - demo version of the OGE in Informatics and ICT 2020.

Additional information about the OGE 2019

When performing the first and second categories of tasks, it is not allowed to use technical devices: calculators, computer technology, mobile phones. Under the ban and reference books, books on computer science.

Coming to the 2nd practical part (Category C), the student receives a personal computer at his disposal.

As for the success indicators, it is enough for the OGE participant to score 5 points to evaluate “satisfactory”. The maximum number with the correct solution of all 20 questions of the OGE is 22 points.

Psychological secrets of successful exam preparation

Passing the exam

“Fortune always smiles on those who work hard,” says an English proverb. I would like to add: "and those who know how to show the results of their work." In the exam, you do exactly that - demonstrate what you have learned. So do it calmly and confidently. Try to change your understanding of the exam - this is not torture, not an 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 in 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 to faint.

2. You should not go to the exam with a full stomach. Breakfast should be light, containing meals 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. Do not "cheer up" yourself with strong coffee. If your nerves are on edge, but you realize that the 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 fruity milkshake will also help support your strength.

3. Music is an extremely effective means of getting rid of pre-exam stress. . When preparing for an exam, turn on recordings of a bravura march, chardash or energetic guitar flamenco, and you will be convinced that your fear and inner trembling will be removed as if by hand. If you love classical music, Bach's Preludes and Fugues for Organ, Tchaikovsky's Fifth Symphony, all orchestral works by Alexander Scriabin will help you. Bach's music, by the way, is very effective if you have to do hard intellectual work. Compositions by Bryan Adams, Tina Turner, Bon Jovi and Riccardo Foli are also set up in a fighting mood.

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

Ways to deal with fear

1 . Stop being afraid! Many are well aware of the 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. It is the fastest, easiest and most effective method overcome feelings of stress and panic. Close your eyes and breathe slowly and deeply. The exhalation should be 2-3 times longer than the inhalation. As you inhale, imagine that you are inhaling your favorite scent through your nose. Exhale through slightly closed lips as if you want to blow out the flame of a candle or blow on a spoonful 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 on inhale, and the words " relax" and " calm down" - on the 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”

Auto-training is an effective technique: the brain perfectly obeys such commands.

3. Learn to never think about failing an exam. On the contrary, one must mentally draw a picture of a confident, clear answer, a complete victory. We get what we think hard about, literally programming ourselves for the final result. And in order for this result to satisfy us, we need to think about the good, setting ourselves up for success: “I will succeed, at the right time 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 being held, students trembling with fear, discussing how strict and picky this or that examiner is, and from time to time saying: “Oh, I will definitely fail today! I got it all out of my head! I'm already shaking!" Do not crowd with them, so as not to "catch" their fear. Handle your anxiety alone, step aside, wander along the corridor, look out the window.

5. Relieve stress. The simplest movements will help get rid of excruciating discomfort. Make a few circular movements with your head, stretch your arms, shrug your shoulders. If possible, box by hitting empty space and imagining that you are punching your fear.

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

6. Do self-massage. A light massage of the occipital region of the head distracts from obsessive fear, and also helps to significantly increase intelligence. Massage of the tips of the little fingers helps to relieve emotional stress, as well as performing yoga for the fingers, the so-called mudras. This word denotes the connection of the fingers in a certain combination.
So, the mudra of the Earth helps with stress, deterioration of the psychophysical state, increases self-esteem and self-confidence. To perform it, press the ring and thumb of both hands tightly to each other with pads, straighten the rest of the fingers and 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.
When stressed, put left hand on the table, palm down. Right hand for 3-5 minutes, massage the intersection point of the imaginary lines of the thumb and forefinger in a circular motion clockwise, while keeping the thumb as far as possible from the index finger. Then change your hand, but now move counterclockwise.

The Executor Robot is able to move through the labyrinth drawn on a plane divided into cells. Between adjacent (on the sides) cells there can be a wall through which the Robot cannot pass. The Robot has nine commands. The four commands are command commands:

up down left right

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

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

top free bottom free left free right free

These commands can be used together with the condition"if" , having the following form:

if condition then

command sequence

all

Here the condition - one of the condition checking commands.Command sequence- this is one or more of 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 commands for checking conditions, using logical connectives and, or, not, for example:

if (right free) and (not bottom free) then

right

all

You can use a loop to repeat a sequence of commands."Bye" , which looks like this:

nc bye condition

command sequence

kts

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

nc while right free

right

kts

Complete the task.

The infinite 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. There is exactly one passage in each wall, the exact location of the passage and its width are unknown. The robot is in a cage located immediately to the right of the vertical wall at its upper end. The figure shows one of possible ways the location of the walls and the Robot (the Robot is indicated by the letter "P").

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

When executing the algorithm, the Robot should not be destroyed, the execution of the algorithm should be completed. The final location of the Robot can be arbitrary. The algorithm must solve the problem for any admissible wall arrangement and any location and size of passages inside the walls. The algorithm can be executed in the environment of a formal executor 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 should output one number - the sum of numbers that are multiples of 3.

An example of the program's operation:

Input data	Output
3 12 25 9

Explanation.

The following algorithm will perform the required task.
