If you go toward Alabama - you’ll be joining more national merit finalists than any school in the country. Tons of smart kids. Frankly, all three schools have tons of smart kids - U of SC is your top Honors College and Arizona, buys kids in like Alabama…so forget acceptance rates, rank and whatever else - these schools are all legit.
Look at Mccullough Medical Scholars. It’s late but they are still taking apps per the website.
