Took my NREMT Cognitive (Written) Test today and, while my stomach was in complete knots waiting for the results, I just found out that I passed and am now nationally registered. I just have to say, EMTPocketPrep is/was an absolute lifesaver. The question format is extremely similar to that of the official test, and you can't beat the explanations provided with each question. They even cited where the answers came from, which just happened to be from the same book and edition my class used. There are plenty of questions and they cover just about anything you might see on the test. I used EMTPocketPrep for about an hour every day for the week before my test, and it really helped with my confidence walking into the exam. That test is no joke, but if you are prepared, you can trust your gut. I definitely suggest using EMTPocketPrep to help keep your knowledge fresh between your course completion and your exam date. I would recommend EMTPocketPrep to anyone who is about to take the test. I'd also like to add that I did NOT experience any of the glitches that other reviewers mentioned. Thank you, thank you, thank you, EMT Pocket Prep.
