There is nothing easy about the NREMT or about the preparation required to pass it. People who think the exam was easy usually think that because they were really well prepared for it.
However! There are some things you can do before and during the NREMT to improve your chances of passing, even if you’re shaky on some topics. If you know the material and understand how the test works, these can be just enough to push you from near-passing to passing.
