I am doing an informal post bac and I basically get last priority with classes. Now I was able to pick up some classes, but the hard science classes that I want are really impacted. A good majority of my classes are gonna be "easy" science classes that are upper div, it has the prefix bio in front of it. So I am thinking as long as its a bio upper div it will count towards my science gpa. Obviously taking hard science classes and doing well is ideal, but that might not be an option for me. Was wondering if taking these upper div science classes is a waste or time or is very beneficial. THe main objective is to get excellent grades to boost up my science gpa, but don't want to look bad with adcoms.
