course rules (for my lectures!)
1) if in doubt, ask questions!
2) if not in doubt, still ask questions!
3) at all times, try very hard to resist the temptation to take notes. Rather, try understanding - I find it much less stressful*
*My own view is that note-taking is a substitute for thought,
and reflects a sadly deficient
However, its never too late to learn better ways! and, anyway, the notes are on the web!
