UC Berkeley or UMich for premed?

Hey all, I was accepted into UCB for College of Chemistry and UMich for LSA.

For Berkeley, is doing premed advisable in the CoC? I’ve heard nightmare stories about 1A/B and 3A/B and I can’t imagine how hard 4A/B would be, especially for a premed who needs a good GPA :\

I’ve visited UMich and feel that the campus is pretty great, but I have yet to visit Cal. I’m wondering whether the stress/workload that seems to accompany Cal is worth the prestige it has over UMich, and if the education and opportunities for research or hospital experience are any better than UMich’s.

Thanks for any insight!
