Hey! I understand the stress you’re feeling right now, but all I can say is that it’s up to you if you feel the need to retake those classes. I actually got a B in Micro lab and lecture, but at the time I was already accepted in the program and still have a 3.9 gpa. I also met a couple people who didn’t have a 4.0, but they were still accepted in the program! If I were you, I would suggest meeting with the advisor at HEC since she can help you out more with your situation and let you know whether or not it’s worth retaking those classes!
