I am starting uni classes tomorrow too. I am going to be using one big back pack so I dont loose anything. It it all in one place and only one bag to remember to pick up.
Mine has two pockets. One for folder, pens, etc and the other for my purse, phone, etc.
Haveing the tow pockets makes it easier to seperate studies stuff and personal stuff and easier to find what you need with out makeing heaps of noise in the class room.

Maybe it's just me, but I never get the matching bag with clothes??? as long as it serves the purpose you need it for with out damaging your back which carrying around heavy books will do, then what does it matter if it is a wrong colour or pattern???

Good luck with your studies.
