I'd preview the entire book.
Then as you need to study different sections, PhotoRead a chapter or two before the section, PhotoRead the section, and then PhotoReading a chapter or two after the sections.
Then activate the section you need to study. Review mindmaps from previous activations, if you have them.
Maintain flexibility because you might discover a better way for that particular text as you are studying it. This too, as I told Jigish in another post, is a great opportunity to apply the 4-step Natural Brilliance model.
