I am presently waitlisted at U-Penn. It is my first choice and I really want to go there. I have already written a letter of continued interest to Gaye Sheffler and sent an update with my most recent grades and honors. Is there anything else that any of you did or think I should do to increase my chances? Is it ok to call and ask to speak to her? If so what should I say? Thank you very much for all of your help.
