Having personally been exposed to his tactics and with a 10 year + background in training, I can tell you his technique and delivery is flawed. Orals are very subjective and ANYONE can fail an oral examination. Outside of basic limitation, memory items and proficiency, anyone can bust systems knowledge specially based on the crappy teaching you get here. I understand at the end of the day he wants to teach, but when you tear someone down with your delivery, the person does not learn.
