Took my national today at 08:30 got my results back at 11:00. Passed. Couldn’t have done it without the Big dawgs book read it every day about 10-20 pages. Videos helped a lot too. Plenty of question’s about scenarios (en route, arrival, and post scene or while in the ambulance) take your time and read the full question you get 3 hours and 30 minutes to take a 110-150 question test plenty of time for each one. BLS before ALS always. Good luck to all and God Speed.
