Hey current med sci, I believe you can call the admissions office and check, but i remember them being flexible with when they receive your rec letters. If i remember correctly, i submitted the day of the deadline (3/1) and had a rec letter arrive a couple days late. Ended up getting an acceptance a week later so everything worked out. Let me know if y'all have any question regarding the program. Its definitely a beast, but if you're willing to put in the effort there is absolutely no reason you shouldn't be able to maintain a 4.0
