UChicago for pre-med now (vs Penn CAS)

<p>I know UChicago has a reputation for grade deflation and has in the past not been the ideal school for a pre med student. However, they've been making many changes and I'm wondering whether it is a now a better pre-med environment (input of current students would be greatly appreciated). How hard is it to get a great (3.7-3.9) GPA? Is it more difficult to do well in science classes than at peer schools? </p>

<p>I also have the option of attending Penn CAS. I liked Chicago a bit more though I think I'd be happy at both and don't know which to choose (i'm also not 100% sure I want to take the pre med route). </p>
