Should I keep all my psychology college books?

I was told that if I'm a psychology major I should keep all my psychology books until I graduate college.



Is that really something I need to do?Should I keep all my psychology college books?
Yes,

You will find that you will forget some stuff and will need to go back and re-read/refresh.

Its a good idea to keep all the texts books from your major.Should I keep all my psychology college books?
Yes, I think that's a good idea. If you need money by selling back your textbooks, then I don't know. You could keep the ones that seem to have good info/explanations that you would go back to (like reference books).



At least you should also file away all your textbook notes, lecture notes, study guides that you have made, review sheets that your professors have given you, essays, articles from class, etc. Put them in those big 3" binders with dividers labeled, one binder for each class (or one binder for each couple of chapters or for each test's materials if the class has tons of work). I find this very helpful.
