Hey, I used Kaplan. I focused on the Qbank. I got 74% on the diagnostic test so they told me to just keep doing questions. I went back and looked at the book if I didn't know something and I reviewed the drugs quite a few times. Tested on June 12,passed with 75 questions. It was hard though,some of the meds I'd never heard of. Kaplan was right on about the style of questions though. Hope this helps, good luck!!!!!!!!!!!
