Kyrssa -
Don't know if you've picked a school yet or not...
I went to PIRE (Professional Institute of Real Estate). They have a couple of locations in the Valley. I went to the one on Val Vista & Southern
The others mentioned are all OK too, so I've heard.
Just remember, no "real estate school" is going to teach you how to be a real estate agent. Their sole purpose in life is to prepare you to pass the state exam. If you pay attention in class, they can all do that. If you sleep or run out of class to text your friends like the chick behind me did for three straight weeks, no school will help you.
Pay attention, listen, ask questions, do the practice exams and you'll do fine.
PIRE at least had entertaining instructors. And lets face it, a lot of that material is as dry as the surrounding desert. Entertaining instructors can significantly decrease the pain factor.
