I will say this flat out:
The Kaplan EMT-B book was written by my former supervisor. It is the biggest piece of :censored::censored::censored::censored: you will ever see in the land. The questions are idiotic and never actually resemble the NR's question types.
My observation regarding the exam was that it had two answers to every question, one was the right answer, usually following the template of ABCs. The other was the "street answer", the one you'd like to usually put down. Follow your protocols, not your instincts.
