In University I tried to understand subjects, rather than just game the system which most smart kids do. Which, by the way, all respect to older folks who go back to University, because you / I really lose that ability; to treat all classes or subjects as puzzles to learn the patterns of, without giving a crap about the subject itself.
I had to game that course, ended up with a 60-something. Glad it has nothing to do with my career, and I suppose the people working in the oil refinery I might have helped design are glad too :P.
Both. Also, serious questions have been answered humorously, and humorous questions have been answered seriously. So a lot has been happening here in a good way.
