You must receive a 75% or higher score on the proctored exam. You are allowed to review the first attempt and then retake the exam one additional time. If you don't pass on the second attempt, you must review all the course information again before your 3rd and if necessary your 4th attempt. We don't charge anything for reviewing the course, but it will take time. We recommend you only schedule the proctored exam when you feel prepared. Also, you don't have to immediately attempt the exam the second time. If you don' t do well on your first attempt, you can review and study for a few days/weeks and then schedule your second attempt.
