We had 10 years school education, then trying to satisfy world standarts they just added one grade (11-th). But there was smth to do with kids who already were studying 10-years program. All this kids just "jumped over" one grade. So it caused a big confusion. And still though we have 11-year school system we study only for 10 years.
Something like that. I never understood it either.
