What worked best for me was to have paper next to me as I read, and every time I felt like I did not fully understand what I read, write down the questions I would need to answer to feel better about my understanding.

Often, the answers would appear later in a chapter. Sometimes, re-reading the chapter would allow me to catch answers to questions I'd missed. If questions remained after reading and re-reading, it was time to talk to someone else who had already studied the material.
