Oh.... It is bad to learn PR on textbooks.
I have the same problems so I tell you how I do it:
1)PR the whole book
2)incubate
2)Searching for trigger words 7-12 max
3)Setting up questions based on trigger words
4)Picking 1 question and moving my eyes down the center of the page.(SR and dipping)- MIND MAPPING them
5)Relaxing 1 min
6)SR again - mind mapping
7)Relaxing 1 min
8)Skitter the whole text to add something to my mind map(MIND MAPS ARE IMPORTANT)
9)After 20-30 minutes that is how long it takes me to make a chapter gel i relax for 5 minutes
10)Rapid read for being sure. I am still a newbie so I want to comprehend as much as i can.
Best wishes,
