Yes, It breaks down the question and tells you why your answer was wrong. It also breaks down the questions in to categories. Cardiology - Airway & Breathing - Medical - Trauma. Plus it has 3 minor subjects, Patient assessment - Newborn assessment - Pharmacology. It gives you 10 question quizzes on each subject. You also have random question quizzes of 10, 20, or 30 questions that you can choose from. The best thing for me was the Test Day Simulation which was 70 questions. I scored 83% on the simulation and passed NREMT with no problem. Check out the site it has a free demo on it. Some people on this forum don't like the site because it doesn't have a million test bank questions. You will see some of the same questions over and over again. I just used those questions for reinforcement. I thought the questions were very similar to those on the NREMT. Check out the site let me know what you think. The only thing I didn't like was that it didn't have any video or charts to explain questions like the old EMT-Achieve site did. There are plenty of sites out there. This one worked for me. Good luck!
