exactly. this is not some game. most people are coming to learn what will essentially be their trade, not some trinket to hang on the mantle. in fact, one of the best, and most intelligent teachers i ever had did not view it as a competition either. his attitude was, if everyone in his course does "A" work, then everyone gets an "A".
and, it's not just about boosting scores. i drink coffee every day. and if I'm taking a course, especially so. it helps me pay attention and retain information. it's about actually learning the material. it's not about winning the National Boggle Championship.
