I took both the EMT-B and the EMT-P versions, although the EMT-B was 11 years ago. For me the biggest difference in taking the NREMT is the way they word their questions. Barons publishes a test prep book that contains five practice tests. Very extensive, one test is in the book, four more are on a CD-Rom. It helps you see the way they ask questions and the answers are comprehensive and explain how they arrived at their conclusion. I believe it is very helpful. I purchased mine on Amazon for 15.00. good Luck!
