After you got your books, you will find out that they are too heavy. Some people carry them in the small suitcase on the wheels. So you will definitely need a locker. And it’s better if you rent it as early as possible because on the third day of classes they only got fourth floor bottom lockers left. Actually, its really easy to get to the lockers of each floor, but upper lockers are of course better. You can rent the half locker like this for 20$ for 10 months (beware they charge you for 30$ and they return 10$ in the end). My coat + My vest + my snow pants + my sweater + my scarf + my food + my books fit here. But you can rent a locker that is double size than this for 27$ for 6 months. 

P.S. I got this sticker and gum on my locker I don’t know if it means something :3
