I honestly just need to maintain a B average or higher to keep myself out of trouble, and to keep my financial aid and whatnot from being jeopardized.
Besides, I've got subjects that I'm actually interested in, or have taken already for this first year since it's just basic classes before I'm allowed to do upper division classes. And, I've got the luxury of trying random classes from different fields to see if there's anything that I like better than the whole biology/environmental/medical thing I've got going right now.
