Hey grasshopper, I went to PENN undergrad, and have had tons of exposure to PENN Med...And I totally love it!
The curriculum is actually a blend of prb based learning/lecture, and is pass/fail during your first year. My advice is to talk to students/faculty...Everyone I know who goes to PENN Med loves it!! You start clinicals earlier, and have more time to explore electives during your last couple years! Philly is no NY, but its also not the worst city to have to spend four years...Obviously I love PENN, and am praying i get in...But I guess, if you really don't have an interest in going, you shouldn't try and convince yourself you'll be happy there...go where you feel comfortable.
