<p>A bio admissions committee cares much less about where you went and much more about what you did as an undergrad. </p>
<p>Best way to get into a top program is to show, as an undergrad, that you can do research. How do you do that? Simple, work in a lab and show your stuff, if you have it. Get a publication in a top journal and you can write your ticket. Not many undergrads can do that, though. Instead, they impress the heck out of the lab head and get a glowing recommendation.</p>
