Zahn's Live Review course was instrumental in my success. They helped me greatly with how to read the questions and understand what was being asked. They also did a great job of focusing on what was more likely to be on the exam. I don't remember any specific questions that weren't covered in the Zahn review material. I would recommend the flashcards and going through each set 2-3 times leading up to the exam. I found that those helped me a lot with retention and there were several exam questions that I got correct due to the flashcards.
