I'm a student at Delta. It's acceptable, but there is definitely something better out there.
If I could start over again I would have went to ATP -
www.allatps.com - request a free information packet. The training is renowned and the price is right
from what I've heard. As others have said take anything from a stranger with a grain of salt and research what school would fit your current situation.
I know nothing of Riddle, UND, Purdue, so I can't comment on those universities. I simply can't afford to go to them.
Good luck, feel free to PM me!
