Jesus Christ guys, some of you need to spend some time in the efficiency thread. I graduated with a 3.5+ in engineering, and am 3 semesters into grad school, and I've rarely had weeks where I had to spend 40 hours on school, usually closer to 25. You don't need to memorize crap, so "studying" beyond doing homework problems is a horrible waste of time. I am pretty sure the people who spend shitloads of time on school outside of class are mostly bbsing, facebooking and watching tv. Most college students are awful at time management. I usually can get 8 hours of sleep unless I have a morning class and was in Aggieville that night where it is usually more like 5-6 with a nap the next day.
