In taking some time in between finishing the course and taking the exam, I felt the Zahn material and class no doubt help me in passing the exam. Eben just having the prestudy material for about 6 weeks prior to the class, it was still very helpful in bringing the info together. The course and instructor were excellent. The test taking tips were very helpful on the day of the exam. I stuck by the recommended post course study schedule, focused on the tips and flashcards, and did all the mini cases/post course practice exams. Those certainly helped in being more confident in answering many of the subjective questions on the exam. Lastly, the course was well worth the cost and time and highly recommend it to anyone prepping for this exam.
