I'm a biology major, associates degree, took "a semester" off which turned into 4 years. I'm getting ready to return in the spring to get my BS, but I have some concerns. First off, my GPA is low. 2.7, to be exact, as I was quite unmotivated and had no goal while I was in school. I now know what I would like to do, which is study molluscs, specifically I'd love to study and research the evolution of nudibranchs. My question is this: Is this a realistic goal? I've been out of the game for so long that I'm really not even sure where to begin, aside from speaking with an adviser of course. Any advice would be wonderful.
