You should inquire about financial aid, and how student loans are repaid. I know a Galen LPN who is repaying her student loan for $59/mo. That's pretty affordable, but she may be paying it for 30 years. I don't know the length of her payback. It would be worth your time to ask those questions. Also, with gas being $3/gal, the drive to Tampa could get expensive. In addition, class at Erwn starts at 7:30, clinicals start at 6:45, and you don't EVER want to be late. There were students in my class that drove from as far as Spring Hill, New Port Richey, and Gulfport. They hated the drive, but always made it on time.
The CNA exam is a snap. You'll have to do five skills, which include handwashing and providing privacy. When I did my test, there was no drape, so I had to remind myself to pull the imaginary drape. I actually talked my way through the skills, so the tester knew that I knew what I was supposed to do. My skills were making an occupied bed (always fun~), range of motion, and peri care (on a mannequin.) When they tell you that you passed, it is an amazing feeling of accomplishment. It's just a warm up for your LPN license.
Best of luck!
