Hi, I attended AMA and was pleased with their EMT program. I really felt that I got a lot out of it and that the instructors were top notch. They are indeed a private school - they were just accredited by ABHES - so take what you will from that. I can only speak from personal experience and my experience was positive. Out of the 10 students in my class (myself included) the 4 who have taken the NREMT have all passed at 70 questions, and I'm confident that the rest will pass too.
The work and tests in class were much more difficult and thought provoking than the NREMT, we did lots of scenarios in their lab and we learned to really think outside of the box. Make sure if you attend that you all work as a team and study hard and you will succeed. As far as their Paramedic and A.S. degree offering........I'm not sure. The A.S. degree should be obtained through a school that is definitely reputable like Broward or Miami Dade College, when you're spending that much money you want to be sure that it will be accepted.
