Hi Jesse
I don’t think it would be harder for the teachers to teach different arrangements. Having said that, they will be teaching THEIR syllabus not necessarily your arrangement.
If you haven’t learned Ben’s arrangement down pat I wouldn’t worry too much since the amount of info you’re going to be learning over the course of the camp will take a while to process when you get home. If you can learn Ben’s arrangement ahead of the camp then that would be most beneficial that’s the reason Ben gives you the list ahead of the camp so you are able to review the content and help you prepare.
