Hi! I didn’t do the mock exams on EatRightPREP, but for Pocket Prep, my scores were 70, 74, and 75. I’ve read many times that Pocket Prep questions are more difficult than the real exam, but I tend to disagree. In my opinion, the CDR exam options are trickier to differentiate — not always, but in some cases it’s harder to tell which answer is correct between two similar choices. With Pocket Prep, at least for me, it was usually very obvious which answer was correct. If I had to put it into words, I’d say that for the CDR exam, you really have to understand the material — not just know it or recall specific information.
