If you have a save a few months before graduation, you can try to use Judo command some more just to make sure. (When you mentioned you counted Judo Club command, did you count only the successful one? I'm not sure about the number, but usually if I keep using Judo command most of the time, I'll automatically have the 1st rate sports university as one of the choices.)I didn't even get the sport university choice. So far I've read that all you have to do is become the club master and have at least fitness 200. Is there anything else I missed?
Also, you need to stay in the Judo club before graduation. (If you quit, you won't be the club master.)
