So, know that it is nearing April 30th, so I thought that I would provide you some perspective.
Depending on what you are more interested in, you should chose accordingly:
UCLA: Very strong research, not so strong patient-care/clinical skills. The reason why UCLA is ranked as highly as it is (or any school is ranked as highly as it is, I am sure you know) is because of how much research money it is pulling into the institution. If you are interested in spending most of your out-of-class time doing research in a basic-science laboratory, then I suggest you pick UCLA. However, if you are mostly concerned with wanting to cultivate your people-skills and be prepared to shine in your residency interviews, I suggest NOT going to UCLA. From personal experience, I can tell you that the UCLA administration is cold and very distant. If you want to have good role-models in medicine--ones that teach you proper bedside manner-- I also suggest NOT picking UCLA. Perhaps the community is nice in LA (and it seems like there has been a lot of discussion in this regard) but I will tell you that it is not the most warm environment in the world.
Michigan: Very strong clinically, not as strong research-wise (but still good). I think there is less bureaucracy with with you would have to deal here. People are a little nicer here and they really care about molding you into a health-care provider. It is BEAUTIFUL in Ann Arbor. Yes, it could get cold. No, it isn't perfect weather like LA all day every day; but, there are sights that are unparalleled in california.
I think a good way of knowing how invested the school is in YOU is taking a glance at their website. UCLA's is very concise; they don't publish their match results. Michigan's has all the events that are going on throughout campus; they have videos up there, very prideful of what their students accomplish. (This is from observation years ago-- things have probably changed). Again, UCLA is an amazing school (but as you can see from my tone of voice) I would choose Michigan.
When I went away for school, I actually became much MUCH closer to my family. It seems like that doesn't make sense, but if you think about it-- you can see the advantages. This is MEDICAL SCHOOL; you will be busy ALL DAY EVERY DAY studying and shadowing. If you were close to home, your parents will expect you home, YOU would expect yourself to be at home. When I moved away, I didn't have the overbearing obligation of helping my siblings with school work, etc. And even though I would LOVE to help them, they became more independent when I left and there was not subconscious tension of "they are keeping me from doing my work." When you pick up the phone to talk to your parents when you are away, you will have more substantial conversations. You will be able to share with them your NEW life, bringing you closer together.
I suggest you go explore for the next four years. I assume that you will want to do your residency in California, right? Well, 4 years away from here would do you good. Go gettem in Michigan, kid. Show them what California has taught you all this time. Then, you will be able to come back as a kick-a** resident to UCLA, UCSD, UCSF, Cedars and the like, and you will be able to share what another city taught you.
Either place you choose will be great (but I would pick UM
).
