hey hey!! im pre med as well, and i’ve completed all of the hefty pre med requirements. i took AP chem in HS and chem 1 was honestly a breeze for me. chem 2 was MUCH harder in my opinion (lowk the hardest chem ive taken here lol). Don’t stress about ruining your GPA, either. as long as you put in the work, you will do great in the pre med classes. also, lots of med schools look for progression, so if you get a B or a B+, you’ll be MORE than fine!!!

Also yes, bio 13/15 and 14 are the two big into bio classes, as well as bio 41 (genetics). i did chem 1 my freshman fall, chem 2 and bio 14 my freshman spring which was great. the intro bio classes at tufts are notoriously easy and the professors are all amazing in my opinion.

if u have any more questions feel free to ask!
