OK, well I am not an MS II, I am acutally a junior undergrad. I can kind of relate right now has I am taking a particularly heavy load and im in class about 8-2 most days, then have to study 4 hours everyday. As far as the skipping lecture approach, I can't do it...I feel like I am missing something even if I am not, and there is always that little bit that seeps into your head even though you are comatose in the back of the room. HOWEVER, I know a couple people who made it through undergrad and never attended lecture...at least classes in anonymous lecture halls(like bio, chem, org, and physics). So my advice, try it and see how it works(maybe dont skip every lecture, just the really pointless ones)...You may be one of the blessed ones who can pull it off.
