IT wasn't a question, if you re-read Island's statement, he said the you have to pay the testing center no matter how many times you take the test. It's pretty standard across all job fields that you have to pay for each time you take a test, SAT, ACT, NCLEX, MCAT, and yes even the basic NREMT exam. You also do not get 6 attempts to pass this test.
My suggestion to OP is to study, study every day like it is your job, and try again in a month or two. Go back to your instructor and ask for help, take practice exams, ask questions here. OP it sounds like you were seriously misinformed about NREMT, I suggest looking at their website some more and educating yourself about how the exam works.
