I have downloaded a good 20+ apps to study for my NREMT test and my EMT class but this is by far the BEST out there - so do yourself a favor a just pay the $5 and download it now.
It has everything Quizzes (broken into categories), flash cards, scenarios, and a tool box with checklists for different medical problems plus so much more!
