These give good info but only a few of these study cards are actually on the exam.
These cards are very helpful. People in my study group have taken then exam and mentioned the cards helped a lot. Highly recommend using them as a tool. (Yes a few are duplicate and had an error, but JCAHPO inserted a sheet stating which one was incorrect and provided the correct answer.)
I received and reviewed cards. I had some with false answers and duplicate cards. not very satisfied with product.
