Belle and Uranium gave good advice. Also, be wary of any situation wherein you are given contrary information on the same figure or on some principal bit of knowledge from different instructors because some of them might not know what they're teaching. So long as two instructors are providing you with the same, good information but using their own idiosyncratic way of speaking, you're OK. You then just have to decode the information given. (But hopefully not.) But if you hear, "I don't do it that way," from an instructor, be wary. Bigotry exists even in ballroom. And, once you have a foundation of understanding, multiple syllabi can be very helpful. I study from 2, and I gain new perspectives, particularly on transitions, all of the time. On another note: A former, 5-time US champion from the 90s challenged me to find a copy of the AM syllibus. To date, I haven't had any luck.
