West Germany used to have 13 years of combined primary school and 'high school'. East Germany had 12. After the unification increasingly in West Germany as well 12 years school were introduced. Often without changing the overall structure of schools, the concrete teaching or the amount of stuff pupils should now.

This has lead to a lot of stress for pupils, and often additional private lessons for pupils, who simply were overstrained.

In Bavaria this move came additional pretty suddenly and without consideration of teacher's opinions.
