<p>Oh, god, I would definitely never say it’s impossible for anybody to get into grad school. It’s just easier for people at schools which are really great in their fields, because they have a lot of resources at their disposal.</p>
<p>Research experience is basically the most important component of an application to graduate school in the sciences, so if you go to a school with a strong tradition of undergraduate research, this will help you tremendously. It’s possible to get research positions at schools without strong undergraduate research programs, but it’s a lot harder, and you have to fight more. </p>
<p>As a corollary, at top schools you can work in the labs of bigshots in the field. Again, you don’t have to work with a bigshot to get into graduate school, but if you have a strong recommendation letter from Prof. Bigshot… you’re going to get in. (I worked for three years in the lab of a Prof. Bigshot. It worked out well for me.)</p>
<p>GPA is also an important consideration of an application package, and students from top schools have considerably more leeway with their grades compared to students from other schools. I had a 3.4 from MIT when I applied, and I got into the top programs in biology over a lot of people with 3.8s and 3.9s. Particularly for top graduate programs, GRE scores are unimportant as long as you do well enough – I mean, everybody who applies has a strong GRE score, so it’s not useful for discriminating between applicants.</p>
<p>The basic gist of the problem is that everybody who applies has good grades, good GRE scores, and some research experience. To make it into the “interview” or “accept” pile, you want to stand out from the rest of the pack. There are tons of applicants from state schools with great GPAs but weak research experience; there are a lot fewer applicants from top schools, and their research experience tends to be more outstanding, so they get into the programs in disproportionate numbers. (My first year class at Harvard next year has 60 kids. 9 of them are from MIT.)</p>

Sure, but the odds are that the kid from the no-name college didn’t have access to all of the opportunities that the kid from the big name institution did. Unfortunately, in the graduate admissions process, it’s not always about you and how amazing you are – you get judged based on the people with whom you’ve worked and the contributions you’ve made to your field.</p>
