Man, you HATE real analysis, don't you?
Anyway, Natural Logic (Essentially Mathematical/Symbolic Logic, taught by a professor who used outmoded symbols ), in which I got a C when I thought I was getting a B or so. The professor was crap (renowned in his field, but a crap teacher) and was single-handedly responsible for me not pursuing a Philosophy major.
Funnily enough, I'm reading through that textbook and other writings by logicians for personal study. Funny, that.
Deductive Logic: The course that did me in this semester....so when i see my old professor next semester i got that for that nikka....went to get tutoring 4 days a week from this fool and he failed me.....
