Everything you need to pass the OGE
You don't have to cram a textbook - all you need is the necessary theory and a detailed analysis of the tasks. An online sample will help you avoid mistakes in preparing your work and learn the examiners’ pitfalls in advance.
All materials on one platform
Notes, cheat sheets, homework with automatic checking - we have collected everything you need to prepare so that you do not waste time searching for information.
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. Classes are held online on Tuesdays from 18:00 to 20:00 and on Thursdays from 20:00 to 22:00.
