Photoreading really doesn't have to be that structured or scheduled. Planning on which days you will do it or not do it or test it or whatever really isn't the point.
It really would be best used WHILE you are sitting in class. The PR step can be used the night before or even better yet, PR every textbook you are using and ask your dreams to "play" with the information subconsciously. Use the classes as activation sessions. Superread, Dip and MindMap during the class. That way when you study you can devote all your time to memorizing everything you need to.
There's alot of "down" time and distractions during classes, use that time for quick activation passes and when the teacher is really focusing, then focus totally on him/her. You don't have to be in a "trance" to do PR or activation, just a mild alpha state and that's easy to achieve even in a noisy classroom.
I wish I had PR when I was in school, I would have done alot better and I probably would be in a totally different career than I am now.
I wish you luck!
