Hi everyone, I've read a few posts on this forum and thought they were helpful enough that I should try to get some help as well. My situation is a little unusual in that I am a third year undergraduate student majoring in biochemistry, minoring in mathematics. I want to tackle biological problems for my PhD, but my experience working in biology labs made me feel unsatisfied with the methods currently employed in pure biological research. Anyways, long story short, I'm hoping to get into an interdisciplinary lab where I can tackle biological problems with more a quantitative and physical approach. Of course, it would've been much better if I had this realization a couple of years ago, but I have to work with what I got. So, my rationale for doing the physics GRE is basically to "prove" to the admissions people that I am capable of grasping fundamental physics in a timely manner so that I can work in a biophysics lab. I have looked over the physics GRE practice question, and I have learned almost all the math necessary for it. I have taken 2 first year undergraduate physics and a second year physics course (thermodynamics). So my questions are: how should I prepare for the GRE given my background? And is my reason for taking it justified? I have about 5 month, but if 3 and a half is doable, I would want to do it mid-september.
