Me again -
but with reference to bio texts, I would keep *everything*. I don't know how most med schools work, but we actually haven't had to buy texts for a couple of our courses - there's this stupid syllabus that is not nearly as clear or detailed as a text would be. I'm realizing now I should have just bought myself a physiology text, instead of trying to wade through the stupid photocopied pap they give us here 🙁
Furthermore, you might find out that you actually own some of the required texts already, and in that case you certainly wouldn't want to have sold those off.
