My D is graduating from USC in a few weeks and thrived there. She is off to med school in the fall. However, I have little doubt she could have attained all that she has at a variety of schools- not just USC. She went there for the merit $$ and special program.
I’d pick Baylor at half the cost and save all that $$ for med school. Baylor is perfectly able to prepare a pre med-- what you decide to do with all these opportunities will determine whether you get in to med school in 4+ years from now.
Btw- it is natural to have doubts about big decisions. Start planning all the amazing things you are going to do at Baylor and these feelings will recede.
