Back to Basics: Perfect Your Note-Taking Techniques
I use a combination of stuff stolen from programming and a cornell-remix to take notes. I study for school and notetaking looks like this: It's on a block of paper (ever tried writing math-notes on a computer...?) with smaller margins on both sides (although one bigger margin left works as well). Notes are sorted according to chapters, chaptertitles are colored (chapter, subchapter) and in caps - so skimming tells me quickly where the chapters notes are. The notes themselves are indented according to context, meaning when I write additional info about something, I indent it below the original info.
