National level awards in dance are not “some awards” - don’t sell her short.
Dance is a time consuming EC, and she still manages a couple more. Just make sure that she emphasizes what goes into high level dance. Time in class, time in practice, shows (don’t forget the shows), the different types of dance, etc.
I do agree, though, that, for biological sciences, MIT is not the best choice, especially looking at her interests and ECs. Based on her profile, I would recommend a couple of liberal arts colleges, like Pomona or a couple of the NESCACs. In general, LACs may be good fits for her. I would also recommend Princeton over Harvard for biology, if she wants to have a couple of “lottery schools”.
Is she thinking of continuing to dance in college?
