I getting ready for a semester of post-bacc while applying and was wondering whether it would be a better idea to retake biochem (where I got a C) or to take an upper level chemistry course. Using my gpa calculator, the difference in my sGPA would be a 3.15 vs 3.19, assuming I get the A in whichever class I pick. I've been getting A's in all of the classes I've retaken so far. I'm taking two other classes for sure this semester, one of which is a retake and the other is not. My cGPA is a 3.28, will be 3.34 or 3.37 depending on whether or not I retake a class.
