The only dispiriting thing about the current math class is that some of the stuff I learned only a few months ago seems to have disappeared out of my head. On the other hand, what's nice is how much stuff I remember with no effort, and how quickly the stuff that was gone comes back. In my defense, the stuff that had evaporated was the more esoteric stuff that I hadn't really focused on - like coin and interest problems. Word problems in general, because they try to get both sides of my brain working in sync, and I'm pretty sure that my left and right side aren't even on speaking terms.
Anyway, the schedule is spotty - started two weeks into the semester, and now next week off because of Yom Kippur. So let's hope I keep remembering these things I already learned, because I strongly doubt there will be enough time to cover what this class is supposed to cover in the truncated semester we're having.
