Do your research, there are several threads already about hybrid emt classes. Just search for them, or look up percom online.
That being said I have went through both the standard emt class and the hybrid emt class. Personally I like the hybrid class. To me its alot more in depth, at least with the school I am in, the instructors compile the power points from multiple sources, not just one source. Another great thing about the hybrid classes are you can do them around your schedule. I was working 40 plus hours a week plus doing the emt class and working with the volunteer fire department.
If you are not a self motivator then hybrid classes may not be for you, but if your working full time, and wanting to get certified then they maybe for you. Just do your research and make sure that you know what your getting yourself into. If your in Texas than look into Percom Online.
