Wow, he took pretty detailed notes in some classes (and strangely very little in others). For the past ~2 years I haven't even carried a pencil to lecture; usually professors have PPT slides that they put online, so listening works better than writing a lot down.
It's also really amazing to see how many courses he took in four years, and most of them must have been pretty tough.
a nice thought, but mit's actually put most if not all of its classes online through opencourseware (http://ocw.mit.edu ).
and (not to belabor the obvious) the learning doesn't come from reading one page cribsheets -- it's from writing them and fighting problem sets till sunrise :P
