For EMT-B, look into the book, "Barrons EMT Exam." I used that and only that to study for my National Registry and I was out of class for like 9 months. It helped me out SO much.
JEMS is good as already mentioned...Brady has a good computer disc in the back of their book that has a good review program for EMT....If you paid attention and read your book you won't have any problems with the Firefighter written exam...it really isn't that difficult.....Good luck....Stay safe........Paul
I ditto Brady. I actually have a practice exam book that I got at Borders, and it's really a good guide. It gives you the answers and refers you to the appropriate material to study in the back as well, even giving you the exact page for the brady textbooks. As far as websites, our local library actually has practice tests on their website for a lot of subjects including fire and EMT. I would say check the library really, sometimes people donate their old study guides and things to the library and those are great reference tools at zero cost. Hope that helps!
