The only way is to get more sleep. 5 hrs a day is too
little.
Even if you pinch,burn,slap,slash,cut or beat yourself, your mind
still cant function optimally. You may not be sleeping during
lecture but you definitely cant absorb what is going on
completely.
Studies is definitely more important than cca. The only way is to
cut down on the time you spend on cca. Sleep more and you will not
have this problem.
As for your training, go and talk to your coach or teacher and
request for advice.
