So, last semester I got mainly A's and one B. I withdrew from chem I and am taking is this summer along with chem II. This semester I can already tell I'm going to screw up calculus, probably get a C. Would it be better to withdraw from calc or retake it? How do med schools view this? My goal GPA is a 3.7+, and right now it's at a 3.7 surprisingly. If I have a high GPA and excellent MCAT score, does retaking a class/withdrawing still screw up my chances?
