hm, I did almost none of that, missed 70% of the lectures, my (computer-taken) notes were a mess and I barely if ever reread them. Didn't miss homework tho. (french engineering school, my grades were hovering between 15-17/20, don't know how that translates to the US system). Before that for the two "prépa" years I was definitely not the most studious given how many evenings were spent playing counter-strike, D&D and warcraft III at the dorm (miss you people), what really helped for the competitive exams allowing to get into the engineering school was doing additional exercises for 2/3 weeks beforehand ; this way I got much better grades than I had gotten for the previous two years. So I'd err on the side of "it's mostly the exercises / homework which are useful"
