Hop-hop.

Revan, the situation with schools varies from place to place. I can't complain about my own school, but I'm in the Moscow region, and it's a physics and mathematics-focused school (starting from the 8th grade). But in general... I think that, on average, the situation is as you described. Simply because even in a neighboring school, which is also considered quite good, my brother studied, and there were a few teachers who weren't entirely adequate.
