My Instructor wanted me to learn both so I could teach others. It was longer, and a bit harder, but well worth the effort. Now if I can't sleep at night, I go over the work, until I doze off or get all the way through it. I asked and answered the qiestions, but was offered help if I got stuck. in my MM, I studied 9 hours, before giving it. The last question I could not get the answer out right, and Brother Joe said something to the effect of "Dog gone it Hippie, that's not the way I have it, but you've said it three times, so you must be right!" I got it on the fourth try.... My shirt was soaked, and that seemed to be the hardest session.
