Just give up, ph4zr 
Give up what? The only notes I take are HW assignments for classes that don't have a webpage listing them, and the occasional "instructor made an interesting aside, look this up later" type scribbles. I'm hardly any sort of "ace student"*, but notes are usually just a waste of paper when
it's all right there in the manual. This applies less if you use electronic means, but some instructors outright ban electronics in class, and then there's the godawful issue of typesetting and diagrams...
*Case in point, the first thing I do when I get a syllabus is figure out how many assignments and classes I can miss to get a passing grade.
Admittedly, mine isn't really a "top notch" school where the instructors bother teaching outside of the book, for the most part. For someone at a decent uni, notes are probably at least -modestly- helpful.
