For teachers and parents

I've already written about this in the FAQ, but just in case I'll repeat it here. I consider your children's classes here as voluntary, and I'm not going to demand anything from them, force them, etc. If a student does not want to study, or cannot force himself, I will not demand anything from him. I simply don't have any channel of influence on him.

But you can influence the student, so if you want there to be some result from classes, then watch how your student is engaged. On the left, in the site menu, there are "Rankings", where you can track the progress of each student. The student can also show you what problems he tried to solve, what was the result of his attempts, etc. There is also a "Rankings by week" table, it indicates who reached what level, as well as by week who solved how many problems. The color of the cell in the "Rankings by week" indicates how good the result was shown by the student in the next week: bright green - very good, light green — average, white — did not even try anything at all. Finally, you can always contact me.

A separate appeal to teachers: it often happens that strong schoolchildren are simply bored at school computer classes. If your student is engaged in this course, allow him to solve problems during the lesson, read the theory of this course! And, of course, if you have strong students — tell them about this course!
