Hmm, so I'm either going to take the second diff eq course (MA 501) or the second linear algebra course (MA 520) in the fall I think. MA501 has a wait list, so I just put myself on the wait list for it and then I'll decide which I really want to take closer to the time. Perhaps even go to both for a class or two and then decide.
Also, I need to get a better idea about if getting a master's the same way I'm finishing my BS is possible, and if so, what they'll count from classes I've taken as an undergrad (as I will have taken a number of the required courses). Not that getting a master's is particularly useful to me at the moment, but it wouldn't hurt to have.
