This isn't entirely AADSAS related, but it's definitely not worth a new thread. When a school (Penn in this case) says something like this:
"It is recommended that applicants submit the Penn Dental Supplemental Application and application fee as soon as possible after submitting the AADSAS Application.
"
They want you to send in your fee/supplement/whatever ASAP after submission rather than mailing, correct? I assume the verbiage is deliberate, but I'm a little wary of sending checks to schools who don't even have my application yet, haha.
