Last year they didn't pull anyone off the waitlist. I agree with the previous poster if this is the school that you want to attend or if it looks like your only hope then it is a no brainer. But the sucky thing about CASE's waitlist is that 1- you have to interview (which can be expensive) 2 - if you make it onto the alternate list they make you put down a non-refundable 1,000 dollars. And last year they didn't even take anyone. So if you have other options then take them....if you don't then I'd go for it.
