Take correspondence, that's what I'm doing. What they do is mail your assignments to you, or you can do them online. You have to budget your time though, set aside evenings to do your work, and the rest of the day you get to play or do whatever you want.
This is good because you do not actually GO to school during the summer, the summer's yours, you just do some work at home. But remember, you have to be good with your time, dont skip daily work at home to go out with friends, self discipline is important.
But dont let that scare you, correspondence is the best way to go about it, and heck, you can even go to summer camp and have your assignements mailed to the camp!! How cool is that?!
Best of luck to you, hope you get into the program you want.
