School notes - keep or throw away?

[RedRoseSAI]

I threw out most of them, but I did keep some that were especially intersting. For example, one of my western civ teachers (who, sadly, committment suicide shortly after retiring) created really easy-to-follow, yet very detailed outlines for each of his lectures. I've saved those, and I have gone back to them whenever I needed a history refresher! Keep the ones you think you'll need, then revisit in a year or two to see if you really do need them.
