I have an oGPA 2.880 and a sGPA of around 2.5. I have a few C's and C+'s in some of my undergraduate lower division courses such as Organic Chemistry 1/2, General Biology 1, and General Chemistry 1. I also have a C or two in upper division courses such as Physiology. I'm currently working part-time (necessary) and will be enrolling in a DIY post-bacc. Should I retake the courses that I received C (-,+)? I don't know which courses I should retake or not. Any help would be greatly appreciated. Thank you!
