Yep. In my country (which is not Germany), the big jump is at ~15. While elementary (1-4) and middle schools (5-8) are +/- the same, gymnasiums/high schools (9-12 or 9-10) do differ. For smart kids, 15 is the age to try to get into the elite profile schools in science or art. Or jump to an overall better school. And shitheads are encouraged to go to "main" 9-10 schools which are straight way to trade schools. Although majority of kids stay in mainstream schools and do what you described. But the system offers a way out for both smart kids troublemakers. Which is nice. Personally I wish kids were more encouraged to aim for a better school at that age. I'm still salty I didn't even try to get into the elite schools since commute seemed too long. Although I did jump to a wee better (and closer) school to escape the overall attitude.
