This is a great question but I do not have that data. I can check with Chrissy (the RKA founder) to see if she can pull that data. I can look into that over the next week and if it is available, I can let you know! We do know that last year we had a 96% pass rate for the exam. This is higher than the overall national average for the exam so we are confident that our materials do give you a boost when you are finally sitting to take the exam.
