Who will benefit from the course?
The course is suitable for students who want to prepare from scratch, work through all parts of the OGE in chemistry and receive a good certificate, as well as those who are preparing to enter a specialized class or college.
What knowledge does the course provide?
In the classes, topics on general and inorganic chemistry, qualitative reactions are studied. Experiments are demonstrated in class and conducted by students in a virtual laboratory.
How is the training going?
Workbooks for the course will help you get the most out of your classes. You can test your knowledge on unique Trial versions of the OGE in chemistry.
We cook from scratch.
We make sure to repeat and structure the entire high school history curriculum
Practice OGE tasks.
Solve unique trial versions of the OGE, compiled according to the recommendations of FIPI and receive feedback
No panic or stress.
All the necessary topics for passing the OGE are in one program
Experiments are demonstrated in class and conducted by students in a virtual laboratory. The course is suitable for students who want to prepare from scratch, work through all parts of the OGE in chemistry and receive a good certificate, as well as those who are preparing to enter a specialized class or college.
The main reason: the course is taught by Alexander Chorbu
Teacher of Olympiad Chemistry at the Sirius Educational Center

The training is suitable for anyone who wants to get a good certificate.
The course is suitable for students who want to work through all parts of the OGE in chemistry: test, part with a detailed answer, experiment.
Preparation will help you get a good certificate, which is important for entering a specialized class or college.
The course provides practice in solving absolutely all OGE tasks.
In the classes, topics on general and inorganic chemistry, qualitative reactions are studied.
Experiments are demonstrated in class and conducted by students in a virtual laboratory.
Workbooks will help you get the most out of your classes.
We manually check samples and homework.
We do not leave the written part assignments for self-testing - this is done by OGE experts.
We check “for real”, like in an exam, and as a result you receive detailed feedback. All this is for the sake of speed of preparation and your results.
A personal curator will answer questions within two hours, 24/7
The curators understand the program and the subject, so they can easily answer your questions about the course and homework - at any time. They know well how difficult it can be to prepare and understand your worries.
The most important task of a tutor is to help you cope with stress and fear before exams.
The lesson lasts 2 academic hours.
