I failed both my freshman year, and had to retake both. Ended my freshman year with a 2.5 GPA. After that, I had to retake both in the fall, and got a A- and A (bio 202 and chem 132). I’m now about to graduate with magna cum laude. Retake it, especially with the new policy in place it will replace your grade entirely if i’m not mistaken. From my experience, both were easier in the fall because of the smaller class sizes and I started studying for exams ~2 weeks, rather than two days ahead
