A mathematical circle (math circle) for 9th-grade students is an extracurricular program designed to deepen mathematical understanding beyond the standard school curriculum. These programs focus on , logical reasoning, and advanced topics that prepare students for high-level competitions and technical university entrance exams. Core Program Objectives
: Provides archived programs and problem sets from legendary circles.
: Mastering techniques required for the All-Russian Olympiad of Schoolchildren and other "Level I" university-hosted competitions.
