He predicted me pretty well: spirals, functional, vi. But even though I have a decent amount of upper-level math experience, I can't say whether I really prefer analysis over algebra. I think it just depends on the problem at hand.
Well, what do you consider "upper-level" math? The original article definitely means graduate level classes, not just advanced undergrad.
FWIW, I'm a physicist and used not rows or spirals but the "columns" approach mentioned by one commenter. :) And I probably couldn't tell you what type of math I prefer.
