What is your passing rate?
This is the number one question we get and the hardest to answer, as it is difficult to get sufficient feedback from our students. The only thing we can document that indicates the quality of our course is the refund rate, as we offer a money back guarantee if you should not pass. Our refund rate for the past ten years has been about 3%. This does not mean 97% pass the exam. However, it does indicate the course is valuable enough that almost all examinees opt to keep the material.
If I should fail the exam, how do I get my money back?
If you purchased the download version, send us an email stating that you failed and want a refund. The refund is normally applied to your credit/debit account that same day.
