<p>Despite what Halcykon said above, Yale’s science programs are among the best in every field (except engineering), and are particularly strong in biology, where Yale probably has one of the top 5 graduate programs in the country. What this amounts to for undergrads is that a biology major at Yale will be at no disadvantage compared to a biology major anywhere else.
Research opportunities at Yale, both working for faculty and using Yale money to do your own research, are tremendous. There is a ton of research going on at Yale, and, again, since biology is one of Yale’s strengths, you will have no trouble finding research opportunities in it.
On the other hand, I would give you very little shot at being admitted as a transfer student. Yale has a tiny transfer admissions rate, and a 3.5 GPA is probably not going to cut it. That doesn’t mean you shouldn’t apply, but realistically, you are very likely to be rejected.</p>
