I've wanted to be a scientist ever since I can remember and have prepared during my entire undergrad to enter biochem grad school. This past summer my research PI suggested that I look into MSTP programs since he knew I wanted to apply biochemistry to environmental health science. The problem is I haven't done a single "pre-med" thing (no volunteering, no mcat studying) and since I'll be graduating this year I'm kind of lost now. I have a very good record for grad school, but I don't want to become lost in the lab. Any suggestions or comments?
