I sense much anger in you. You must release your anger and quiet your spirit. Then you will hear the force speak to you.
I think you've gone over the material more than enough. Start Playing with it. You seem too tense. Your goal of wanting high-speed photographic memory may be creating too much tension. Set yourself a smaller goal, and listen to yourself.
NOPS is for when you use the system, not when you review the course.
May the force be with you.
