I am sorry. I am responding so late. I have been out of town on vacation. I studied all the systems of the body and their main functions. Definitely focus on cardiovascular, respitory, and the brain. I also googled a lot of blogs of people who had previously taken the Kaplan, since there was very little study material. Hoped this helped some. Good Luck!!
Fall 2019 Hopeful. Wanted a place where we could keep in touch as letters start arriving. Took Kaplan today. ((Passed)) Adver advised we should start hearing something by Mid-Late September. Good Luck everyone!!
