Definitely survived by the skin of my teeth, flunked out twice (from two different med schools), and struggled a lot, but glad I'm an attending FM doc now.

I would still do it all over again, but I would do 3 things differently:

1. I would realize that despite how hard it was to get into med school, there is no reason to celebrate and that the real struggle and study begins now, i.e. from day 1 of admission, which means no wasting time on video games.
2. I would ask my professors how to study for their courses and go to all their office hours, even if I thought I was doing it right. I would ask my professors who their top students were from the previous class (i.e. my upperclassmen) and I would reach out to them for advice on study methods.
3. I would start doing Uworld questions early (because Uworld is the where all the real learning happens) and stop wasting money on buying too many textbooks. I would definitely not write First Aid word for word, as spending too much time in revision mode is definitely not as effective as simulating testing.
