The past couple of months I was pretty set on applying to Yale SCEA as well as some elite publics. Recently, though, I've been considering to Harvard SCEA. I like Yale slightly more than Harvard because it's more laid back and social IMO (based on my campus visits). Why I'm considering the switch:
1. I've heard that while SCEA at Yale isn't really an advantage because of the stronger pool, Harvard actually gives a slight boost.
2. Harvard also gives a slight boost to Massachusetts residents, which I am.
3. Finally, I've heard that applying early to a school can help you in the regular round, as it gives you experience in the application game, so you can adjust your essays, help your ECs, etc.
