I will have completed (in a couple of weeks) the standard suite of pre-requisite courses as a returning student, and will be applying starting in June. Next fall, I have some options. I could take, say, genetics or biochem. Or I could use the time doing undergraduate-level research at the local medical school. I won't have time to do both. Some of the projects underway look interesting, and that seems to me like a great experience, but I've also heard that upper-level science courses can be helpful. What do y'all think? Thanks for your opinions.
