You shouldn't have a huge problem at school if you're commuting via bike. If you are lock it up where other people lock up -- usually around the greens/library/computer center/etc. If you are living oncampus and your bike is expensive you might wanna just bring it in all the time. I did that with no problem. Other times I would lock it up across the street on a fence I could see out of my window. Also no problem. It depends on how comfortable you are, the size of campus, etc. There were certainly no infamous "vans with carjacks driving through, stealing bikes en masse." I used a krypto mini.
