Hi SB,
Nope, no essay with the WSU supp. There are several 'tabs' and 'sub-tabs' of data that you need to complete. These include things like biographical info, information concerning vet/animal/research experience that you DIDN'T include on VMCAS, pre-req coursework, educational history (for both you and Mom/Dad), as well as your reasons for wanting to attend WSU. The information isn't bad at all, but the form can be very buggy. If you're wanting to apply, I wouldn't leave the supplemental for WSU until last minute (just in case you run into problems saving the data; entering the data isn't an issue, but saving it can be). I agree that it's surprising that the school asks for the fee up front. Good luck
