I'm with you in the bureaucracy sucks cathegory. Well Germany is kinda the land of bureaucracy. Maybe you should just accept it as it is I'm a silent rebel myself but I learned where patience (I learned a new word:b ) can get you. My mom always thought I won't get through school without repeating a year but I made it. You just have to prove what you can do not only to others but also to yourself. You have to know that you can cope with everything that they throw at you.
Maybe you can take a look at the 'baby school' and talk to some of the teachers or the principal about your problem
