<p>While I agree with Dirt McGirt's ranking (I'm in biology), I think it's worth noting that graduate admissions are generally more holistic than undergradute admissions, and every aspect of the application is important.</p>
<p>Moreover, the relative weight of factors will depend on other aspects of your application -- if you have a gorgeous recommendation from a famous professor, for example, or if you have previously worked with a professor in the department to which you are applying, you may be forgiven quite a bit in the way of GPA and GRE scores.</p>
