Understand all topics of the Unified State Examination in chemistry
The main goal of the teacher is for you to understand the subject itself, to see its structure and logic. Then in the exam you will cope with the task even in an unusual wording that was not found in the trial versions.
Manage your time and don’t worry about running out of time
From February to May, you will have time to complete all tasks with short and detailed answers, learn about this year’s changes and design details. Teachers will pay special attention to the tasks from the second part so that you can earn maximum points.
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. Subject classes are held online twice a week on Tuesdays and Fridays at 16.00 (Moscow time). Practice takes place online once every two weeks on Fridays at 20.00 (Moscow time).
