Years later, a school teacher myself, I would try to have my students not only take in important information by reading or hearing, but also by discussing it, drawing it, and writing about it. The more senses that were involved, the deeper the material was absorbed.

They include writing more questions of important parts you have highlighted, orally answering some of the questions if you can, reviewing your notes, creating flashcards for important concepts and terminology, rewriting the table of contents using your own words, and building out a mind map.
