So here's the thing, I just heard back from a university with an REU offer. I'm super excited and this was definitely my top choice, however the research is in computational biophysics. Again, I'm definitely excited to learn more about the research, but I'm also terrified. I grew up going to a very religious school, and as a result I have never, not once, taken a course in any sort of life sciences. I'm looking at the research of my mentor, and it looks like Greek to me. The computational part is something I'm comfortable with - I've had some research experience in computational particle physics and a few publications. But biophysics is a whole new world to me. On a scale from 1 to 10... how in trouble am I?
