What is more attractive then the form of the OGE (GIA) for graduates of the 9th grade of 2019? Carrying out direct certification in this new form allows you to get an independent assessment of the preparation of schoolchildren. All OGE assignments(GIA) are presented in the form of a special form, which includes questions with a choice of answers to them. A direct analogy with the USE is drawn. In this case, you can give both short and detailed answers. Our website website will help you prepare well and assess your chances realistically. Besides, GIA and OGE tests online with checking answers help you decide on the further choice of the profile class of high school. You can easily evaluate your knowledge in the chosen subject. To do this, our project offers you various tests in a number of disciplines. Our website dedicated to preparation for passing the GIA 2019 grade 9 online, will fully help you prepare for the first serious and responsible test in life.
All materials on our site are presented in a simple, easy-to-understand form. Whether you are an A student in your class or an average student, everything is now in your hands. It will not be superfluous for you to visit ours. Here you will find answers to all your questions. Be prepared for a difficult test of the OGE, GIA and the result will exceed all your expectations.
Part 1 contains 19 short answer tasks, including 15 tasks basic level complexity (the serial numbers of these tasks: 1, 2, 3, 4, ... 15) and 4 tasks advanced level complexity (the serial numbers of these tasks: 16, 17, 18, 19). For all their differences, the tasks of this part are similar in that the answer to each of them is written briefly in the form of one digit or a sequence of digits (two or three). The sequence of numbers is written in the answer sheet without spaces and other additional characters.
Part 2, depending on the CMM model, contains 3 or 4 tasks high level complexity, with a detailed answer. The difference between examination models 1 and 2 is in the content and approaches to the implementation of the last tasks of the examination options:
Exam Model 1 contains task 22, which involves performing a "thought experiment";
Exam model 2 contains tasks 22 and 23, which provide for the execution laboratory work(real chemical experiment).
Scale for converting points into grades:
"2"– from 0 to 8
"3"– from 9 to 17
"4"– from 18 to 26
"5"– from 27 to 34
The system for assessing the performance of individual tasks and the examination work as a whole
The correct performance of each of the tasks 1-15 is estimated at 1 point. The correct performance of each of the tasks 16-19 is estimated as a maximum of 2 points. Tasks 16 and 17 are considered completed correctly if two answers are correctly selected in each of them. For an incomplete answer - one of the two answers is correctly named or three answers are named, of which two are correct - 1 point is given. The rest of the answers are considered incorrect and are scored 0 points. Tasks 18 and 19 are considered completed correctly if three matches are correctly established. Partially correct is the answer in which two out of three matches are established; it is worth 1 point. The remaining options are considered incorrect answers and are scored 0 points.
Checking the tasks of part 2 (20–23) is carried out by the subject commission. The maximum score for a correctly completed task: for tasks 20 and 21 - 3 points each; in model 1 for task 22 - 5 points; in model 2 for task 22 - 4 points, for task 23 - 5 points.
To complete the examination work in accordance with model 1, 120 minutes are allotted; according to model 2 – 140 minutes

Changes in the demonstration versions of the OGE in chemistry
In 2015 in demo versions of the OGE in chemistry was the structure of options has been changed:
- The variant began to consist in two parts.
- Numbering assignments has become through throughout the variant without letters A, B, C.
- The form of recording the answer in tasks with a choice of answers has been changed: the answer has become necessary to write digit with the number of the correct answer(not circled).
Since 2014, demonstration versions of the OGE in chemistry represented two models. These models differ only in the practice-oriented tasks of the last part, moreover, model 1 is similar to the work of previous years, and model 2 provides for the implementation real chemical experiment (tasks C3, C4 in the 2014 version and tasks 22.23 in the 2015-2016 versions). To organize and conduct a real chemical experiment in model 2 Federal Institute pedagogical measurements methodological materials were developed. The choice of the exam model is carried out by the educational authorities of the constituent entities of the Russian Federation.
IN demo versions of the OGE 2016-2019 in chemistry compared to 2015 demos there were no changes.
In 2020, only one demo model OGE option in chemistry, in which, compared to the previous year 2019, the following changes:
- increased the proportion of items with multiple choice answers (6, 7, 12, 14, 15);
- increased the proportion of tasks to establish a correspondence between the positions of two sets (10, 13, 16);
- task 1 added, providing for testing the ability to work with textual information;
- V part 2 included task 21, aimed at checking the understanding of the existence of a relationship between different classes inorganic substances and the formation of the ability to make equations of reactions that reflect this relationship. Another controlled skill is the ability to write equations for ion exchange reactions, in particular, the reduced ionic equation;
- added mandatory practical part, which includes two tasks: 23 and 24:
- V task 23 from the proposed list, it was necessary to select two substances, the interaction with which reflects Chemical properties specified in the condition of the assignment of the substance, and make two equations of reactions with them;
- V task 24 it was necessary to carry out two reactions corresponding to the compiled reaction equations.
