Credit cards in college advice~

Hello~ I've done the mistake of taking on not one but two other credit cards. Now I'm more worried than ever before about my credit. I got the cards to establish credit but got over my head and I'm trying to keep my credit score up to stay in college, and to have good credit in general. 
Any ladies out there who overcame a situation like me? Any tips on how to pay of credit cards quick or just advice in general.
And yeah I was irresponsible!
