Should I?

I can't cope with my studies. I don't know why... I think its because I think more for my CCA than my studies which carries marks... I've been thinking if I should quit my CCA, but I have the potential in it. Should I quit? or should I just master my studies with my CCA? I know that can never be possible, but how? So maybe, I should just quit... but I've been always done my CCA project properly. Now that my CCA teacher knows that I have the potential in it too. So, is there a need to sacrifice my dream to become a very good IT person? Is it worth it? Maybe I should give it a thought once again. Or maybe, that's my final descision. Or after this project... I shall quit. YES!!! GOOOOOOOO this is my firm and final decision.
