Any tips or University?

[Canerican]

I got in the University of my choice, University at Buffalo, any words of wisdom before I enter my second week. I am sure most people here are well educated, so if you have anything useful, please post it.
By my schedule looks like this: (hours= credits in America, 160 hours for a degree)
English (3 hours)
Physchology (3 hours)
Management (2 hours)
Math (4 hours)
Microeconomics (4 hours)

Also I am going for a business degree, I may change course (pardon the pun) and change majors, I am not sure and it is too soon to tell.
