If you have to retake a portion of or the entire exam, this should be completed within 6 months of the original exam date. If six months pass, you must take both the written and practical exams again. Scheduling one on ones with your Instructor Trainer is highly recommended to work on specifics. IF you take your exam for the first time and fail both portions, you may retake the exam within 6 months. If you fail both portions a second time, you must wait 6 months before testing again.
