I'm in a new dilemma now. I'm not an A-student in the sciences as I've said, more like C's and B-'s, and I'm starting to doubt whether I should even consider the science field of any type If I do not that well (which I'm striving to be) in high school, is there a chance that I can exceptionally improve myself somewhat to an extent in university/college (That doesn't mean I'll quit working hard in high school!)? BTW, I'm aiming for the AP/IB Chem. grade this semester be a B- because last semester was an exact 70

I really love the subject of science, but ironically I'm not a professional at it (maybe I'm not seeing things more clearly?).
