i spoke to the deans of admissions 2 years ago when he came to my school and he pretty much said that the program was set up by the previous dean of admissions and he doesnt really believe there should be that many spots for D.5 and he is going to slowly cut down the number.
also, the course load for the D.5 students is a joke. i have a couple of them in my class and apparently they only take graduate phis and do rotations the rest of the day. shoot, i have a MUCH MUCH harder schedule than they do and im only doing a certificate program.
my take is that if your given an oppurtunity to do the D.5, do it. its easy the first year and will make second year easier cuz you will take 2 less classes. BUT if you get accepted to another school, which may not be as highly ranked as VCU, go! dont waste a whole year.
