I read all the main theorems without even reading any of the definitions and examples for the first pass while at the same time I write down any questions I have with a reference to the theorem it pertains. For my second pass I go back and look at the examples to see if they answer any of the questions I wrote down and write down more questions referencing the examples. For the first two passes I don't try to answer any questions. I simply try to engage the material. Finally I try to answer all the unanswered questions and work some of the exercises and write down more questions if there are any left.
