Need Advice

I am doing a Post Bacc and got Straight C+ in both Chemistry, Calculus and Physics 1. I suppose I am looking for some advice on what to do next. The school im going to is very hard to get a good grade, cut throat and Im not understanding what im doing wrong. Trying to figure out if I should keep trying or call it. Thanks! Or any suggestions from someone who was in the same situation like me.
