You are not building the information in layers by resorting straight to a raopid read. I think textbooks should always be activated in layers with the rapid read as a finale in the week or three before any exams.

Also check your purpose. Your approach indicates you're skimping on that too. Which will give you poor results.

If you're not asking mind probing questions during activation how on earth are you going to know the answers when a test comes along?

Ask questions of the book if you're not asking questions you are passive reading and not rapid reading.
