Read the title and anywhere from the first few paragraphs to the first few pages of the chapter to figure out how the author is using this chapter and where it fits into the argument of the book. Then skim through the headings and subheadings (if there are any) to get a feel for the flow. Read the first sentence of each paragraph and the last. If you get the meaning, move on. Otherwise, you may want to read the whole paragraph.Once you’ve gotten an understanding of the chapter, you may be able to skim over whole pages, as the argument may be clear to you and also may repeat itself.
