Express course in preparation for the OGE in physics for grade 9 - free course from Foxford, training 4 months, date: December 4, 2023.
Miscellaneous / / December 06, 2023
According to the rules of 2023
We constantly monitor changes in the exam and adjust the lesson program according to them.
In an atmosphere of support
The course curators will help you believe in yourself and cope with anxiety.
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, class notes, homework with automatic and manual 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
