As mentioned before, there should be some practice books in your local library. I'm in Canada, and even in my local library there is a book of NREMT questions. I have been studying everything I can get my hands on these days (classic presentation of the over-eager rookie ) and passed all three practice tests (with atleast 80%). I'm not sure if all practice tests are created equal, but studying should definately improve your outcome next time. Good luck!
