Many reasons... First being I don't want the school to get in the way of my plans. Away rotations have to be preapproved. Now I know other schools do this but the way NOVA makes it seem that a no answer is very likely. Second required summer programs... When am I going to study for USMLE and/or COMLEX? Third, they are the worst organized school I have seen so far. Fourth, Area prestige... They are competing with UM,FIU, and FAU all are vastly better schools. Fifth, I never really ranked it very high to begin with. Sixth, their interview selection processes makes no sense, I have studied it over the last two cycles and I still can't tell if it is random, based on top grades and scores, forgiving, competing ideas or all of the above. Seventh, the school is insanely expensive. Finally this is just one few schools that I have met multiple graduates from and to be honest the way they practice medicine I found to be unethical and/or dangerous. How much of that reflects on NOVA I couldn't tell you but I believe it is a factor.
To be honest however if I was interviewed and accepted and I was not accepted by any other school in the time window to pay my deposit. I would pay them and go there if I was not accepted to any other higher ranked MD school because I can't afford to hold onto multiple DO acceptance.
