Our teachers — competition participants, authors of methodological developments
They know how to interest every child, taking into account age characteristics. Each lesson is an exciting journey into the World of Knowledge!
Let's look at the main topics of the program
The child will not have to study the material on his own and cram it without understanding. The teacher will explain even complex topics in simple language, and presentations and interactive tasks will increase interest in the subject.
Let's consolidate knowledge in practice
After each lesson, a small homework task that will help you practice the material you have covered and practice before the test.
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. Your personal curator will answer your 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.
