Um, you want to go to a place where there are not an intense crush of pre-meds (or less of them). Unless you think that intense competition is a good thing, but judging by you being extremely stressed by an abundance of choices (and the IB exams), I would say it isn’t.
@warblersrule, at JHU, there is intense competition just to get a committee letter. That is, justtoreceivethechancetoapply to med school. I believe Duke also uses the committee letter system and WashU also issues a committee letter, but I don’t know if it is as competitive just to receive one at those schools.
Speaking of which, also look to see what schools issue a committee letter.
A committee letter is sort of a seal of approval, so it’s good to get one at a school that typically has 80%/90% of med school applicants getting in to med school, but it also means that if you don’t receive a committee letter from a school that issues them, you’re dead in the water and really should consider a different career because med schools won’t admit you. Contrast with a school like UMich which doesn’t issue committee letters so anyone can apply anywhere and the med school admit rate is around 50%.
The percentage of aspiring pre-meds is almost certainly understated a good amount at JHU because of that committee letter system. You should research other schools too.
