hi dave,
my understanding for COMP was that students on the waitlist were all reviewed together instead of having a high, middle, low list. Therefore, anything else positive that could hit the folder will help your chances.
check out things like great spring grades, awards or honors, research opportunities, etc. Write a professional looking letter and ask for it to be noted in your file.
good luck to you, and everyone who is waiting. There IS a spot for you!
