As in saving all of your homeworks, tests, notes, etc?
I notice i did this with university work as I never knew when I would need to come back to it again.
Just curious, do you hold onto your old stuff?
I only keep the books and notes from the degree or trade/professional school I am in, with some exceptions.
HS stuff is all gone, as is anything before that time.
Junior college stuff is gone except for some recent texts that are computer repair and computer programming related if they are fairly current, but when outdated, they get recycled.
University stuff is all gone.
Business graduate stuff is all gone.
I may keep my law school texts, but if no relation to the bar, or to law practice, as most people say, then I will donate them to the next class as is the tradition.
I admit to keeping stuff that I never officially studied, like my physics stuff and theological stuff, but I did a couple of semesters in an unaccredited bible college which only distributed knowledge, and not diplomas, and it turned out to be more beneficial than the standard HS/college training I had, though latter were "accredited/recognized".
