Remember that the material included on the certification examination is material identified by your professional peers as relevant to and required for your daily practice. There is no limit to the number of times you may sit for the certification exam. If you aren't successful the first time, you will at least have a better idea of the content and of the type of questions included on the examination. This will help you prepare to take the test again. Not unless you tell them.
Fear of failure is the largest single barrier to individuals taking the exam.
