A one-week course covering school subjects in just seven days. Children will study with leading teachers from the M.P. Shchetinin Lyceum. The immersion method with his students was tested by us in August 2020. The results were impressive: all children improved their academic performance, and many were invited to participate in national academic olympiads. Students, parents, and teachers were equally enthusiastic. During the session, children study academic subjects and also take part in active recreation: running, gymnastics, massage, breathing exercises, folk dancing, hand-to-hand martial training for boys, and the “Charovnitsa” program for girls.
