For those that have been accepted already, how long do the schools give you to decide to enroll in their school?
Usually, they give you 2 weeks to pay a deposit to hold your seat from the day the letter is sent.
It depends on the school, for example for PCO they will refund you back $400 out of the $500 deposit. But I think the fee should be around the same for the schools, around $100, which isn't that much for reserving a spot.
