JB Learning DOES help...
I just wanted to chime in about the JB Learning website spoken of here. I used that service and it DID really help out! It's probably THE best helper you can buy online. You are given "test" questions as you take a practice test. If you answer incorrectly, you are immediately told that you missed the question, and given the rationale for why another answer was correct. This is a learning step, and very useful for the NREMT. You buy an account to use the service for one year. Beware, they have a limited number of questions, so after a while, you will be seeing the same questions again. Thankfully, since this is computer and web generated, the answers get jumbled up so you don't automatically select the same letter (a,b,c,or d) everytime you see those same questions.
In addition to this, I have to say that NO AMOUNT OF QUESTIONING will help you unless you know the Patient Assessment protocol, and the sequence of events that you have to step through. There is just no substitute for knowing Patient Assessment. I mapped the assessment protocols for medical and trauma in a timeline. Then I made adjustments to that timeline according to the suspected medical issue, or trauma issue at hand. Then I memorized that timeline. If I had done this on my first NREMT attempt (I went to all 3 tries people), I am sure I would have nailed it then.
