yo just do ''Mad Reps'' reps are your best friend in jiujitsu. there the only thing you can control. you can't control how good other dudes are. you can only control how many reps you put in. make jiujitsu yours & take it home with you don't just leave it at school. do reps at home with people that live with you & if no ones willing to practice with you you can still rep the basic movements by yourself. and if you partner up with someone who's lazy in class don't let them cheat you out your reps. 10 reps minimum is a good starting point.
