waitlist advice needed

[Resendes8909]

I am waitlisted for my top choice program... Was informed two weeks ago by e-mail and a letter from the department head. Any advice on improving my chances?

I have already e-mailed the department head - I tried not to sound like I was begging him or anything, but I truthfully admitted that this program is my top choice for various reasons.. He replied with a courteous but short e-mail letting me know he will take into consideration that if accepted I would definitely attend.

I called the grad coordinator and left a message recently too. I mainly want to know if the waitlist is ranked.

Any advice?
