Leaving it Behind

I am now the proud owner of my very own checking account. I feel so old and responsible, two things which I definitely don't consider myself. However, I need an address for my checks, and my school isn't informing the freshman of their box numbers until August 15th. How hard is it to assign a box number? They think August 15th is early? That's like two weeks before school starts! A little more notice would be nice, you know, in case someone wants a checking account or something like that.
