Chance Me for UCs + Reach Schools (USC, Cornell, Brown)

I think you may benefit from adding colleges that would be superb for the study of biology, but which also offer a notably strong focus on undergraduates. This would be the case at the three schools mentioned above. You also indicated some subjective aspects in your post that suggest you might be a good personality match for one or more of the three (for example, it seems you like cities, to which two of the recommended schools offer proximity).
