+1 Jcleppe.
It may appear simple to do on your side, but it is by no means a sure shot of it occurring for the reasons Jcleppe. It is not a simple process for them, because they have to look at every unit, and when you move one student it has a domino effect, not only on the size of the unit, but costs too.
Be prepared to pay out two deposits. The first to the college that you now have a scholarship, and the second to CCU. Most colleges want the deposits/answer of matriculation by May 1st. Thus, this is a conversation to have with the folks.
~ Contact the bursar at both colleges, sometimes they will be lenient and say that they will refund the deposit. Some are strict and you can be out 500 bucks.
~ Additionally, you need to look at the fact that most schools have overnight orientations. It is 1st come, 1st serve. They usually start doing it as early as mid-june. This is when you sign up for classes. The longer you wait to attend the orientation can mean at small colleges those perfect class times starting at 10 are closed out and now your only other options are 8 a.m or 3 p.m. If you wait to register until you know for sure you are attending you are risking getting that funky schedule. You will get all of your classes that you need, because the school knows how many of the classes that they need, but probably not the schedule that you want.
