Thanks Photoread4me for your reply,
I think I am not sure what do you mean by textbook? Maybe the book I am reading is so. However, I work in a business which has no relation with history, so I have no pressure what so ever while reading, it's just a hobby.
Regarding the multiple passes do you recommend doing it on a book that I have read before so my comprehension will be better or a new book so it generates more curiosity or the same book I have already photoread several times?
Should the mind mapping be done even at this level of comprehension or wait until I feel I'm fairly competent Photoreader and rap it with the mid-mapping?
