I like your revised list! You have safeties in state (remember that safety means for both acceptance and affordability) and reasonable targets/reaches. Good job!
Regarding your Maybes… W&L is an outlier since it is so much smaller than the others and in a rural location. It also has a fit that does not work for everyone. My D really likes it, except for the location (she preferred suburban), but that was not a deal breaker for her (especially after she was awarded the scholarship). If it still appeals to you after consideration, I will add that it has wonderful pre-health advising and an amazing alumni network. It has a clearly stated goal of improving diversity and uses the Johnson Scholarship to attract high stat diverse students. My D had multiple Zoom sessions with faculty and current students when she was making her decision and felt it was a good fit for her.
Soooo… UPenn & Brown - If you apply to them and are accepted, will your parents pay $80k per year (without loans)? How will you feel about asking them to pay that given you stated you were trying to minimize cost for undergrad (presumably to save money to pay for med school)? If they do pay $320k for undergrad, will that impact your ability to pay for medical school? I will let you answer those questions yourself and if you still want my thoughts, I will share them.
