<p>Pick the school where you think you’d be happiest, because all of these schools offer fine pre-med curricula and you’ll do the best where you’re happiest.
Moreover, you should keep in mind that a high percentage of students who enter college as pre-meds don’t finish it that way, so that shouldn’t be the sole basis on which you choose anyway.
Tufts’ pre-med curriculum is great, by the way (as it is at most schools that have their own med schools).
Good luck!</p>
