10 years exactly, or a bit more than that?
The reason I asked is that CS enrollment changed dramatically after the .com bubble burst. When I applied to CS a little more than 10 years ago the bubble was in full swing, and only the top 1/4 of applicants to the program had a hope of getting in. Transferring in was a no-go.
2 years later enrollment had dropped so low that the quotas were gone and transferring in was easy. Application numbers, as far as I know, still haven't recovered to bubble levels.
