I'm getting ready to take the RHIA Exam at the end of the month and have heard conflicting things about what study guides are best. All of my friends who have taken it say the PRG was not helpful. For those who have taken it and passed recently, what did you use to study and what guide do you think is most helpful. I don't want to waste my time studying something that won't help me on the test. TIA
