Best Place to ED (low act, solid everything else)

To which school(s) were you accepted to a fly-in program? That school(s) would likely represent your best chance of admission. All T30 schools will be a reach, and your ACT is low for most, if not all, T30s…what that means is you need to have at least 4-6 target schools and 1-2 affordable safety schools on your list.

Run the net price calculator (NPC) at the schools on your list to make sure they will be affordable. You may need your parents’ assistance to do that, as they will require your family’s financial information–salaries, tax returns, etc.

Edited to add: there are many CC threads about pre-med strategy, it may be helpful for you to look at those. Some people will advise that pre-meds be certain to be in the top 25% of GPA and test scores at their ultimate school…the thinking being to be more toward the top of the class academically speaking. Med school required courses will have competitive curves anywhere and it’s probably more pronounced at the more selective schools.
