pre-med at uchicago

<p>Hi,
This is a question for current pre-med students at uchicago. I recently switched to pre-med here (my major is in the social sciences). How difficult has it been to maintain med-school worthy grades in pre-med courses? I'm trying to get a feel for how I measure up, if I even have a chance at med school. Are there U of C pre-meds who have been rejected from every med school they applied to just because they had B's in science classes? I have found A's very hard to come by in gen chem especially. Thanks for any insights you can offer.</p>
