Getting ready to win
Study at Foxford and win the Olympics

Competitive spirit
Rate yourself among the strongest in this subject

Let's study the main thing
We teach methods, principles, approaches to understand mathematics and cope with any problem

In 31 lessons we will study all the important topics for success at the stages of VSOSH
The course program includes all the most important sections of Olympiad mathematics: the study of processes (invariants and semi-invariants), the method of locus of points, functional and Diophantine equations, which are not studied in school lessons.
You will be able to understand how to still solve non-standard problems

You will become familiar with new methods and ideas, the confident use of which will allow you to solve any Olympiad problems. Even non-standard tasks can be standardized.

“Forewarned is forearmed!”‎

Main reason: The course is taught by Vladimir Sharic

Lecturer at the Faculty of Mathematics, Higher School of Economics
Chairman of the regional commission of the All-Russian Secondary School for Mathematics in the Moscow region

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.

Cobminatorics and logic
This section studies topics in combinatorics: counting options, graphs, Dirichlet's principle. The solution of algorithmic and text logic problems is demonstrated.
- Basic rules of combinatorics
- Combinations and placements
- Invariants and semi-invariants

- Evaluation and example

Geometry
The section examines the geometry of triangle, circle, area, and combinatorial geometry.
- Inscribed and circumscribed quadrilaterals
- Triangle geometry
- Square
- Combinatorial geometry
- Plane transformations
- Point degree. Radical axis.

Algebra
The section includes the idea of parity, divisibility, the fundamental theorem of arithmetic, the concepts of GCD and LCM, modulo comparisons. A separate lesson is devoted to quadratic trinomials.
