The time for preparing homework should not exceed 3.5 hours a day: "Experts in the field of education claim that the main measurable and therefore objective indicator of student overload is the excess time a child spends on homework. It will not exceed 1.5 hours in grades 2-3, 2 hours in grades 4-5, 2.5 hours in grades 6-8 and 3.5 hours in grades 1-1. There is no homework."
