College Question ??? if anyone is willing to help please don't hold back

Okay so when I was looking at the tuition prices it says $220/billable hour + fee 
So how does it work. Am I paying $220 in all plus the fee but they let students pay little by little per class? Or I'm stumped :/
For those who take online schooling , how do you like it? Is it better than physically being in a classroom? How do I make sure my credits can transfer to a university of I decided to do online schooling?
