Skimming and Scanning. Your perceptions of any written text are deepened through familiarity. One of the most effective methods for beginning the kind of thoughtful reading necessary for academic work is to get a general overview of the text before beginning to read it in detail.

Skimming and scanning are two very different strategies for speed reading. They are each used for different purposes, and they are not meant to be used all the time. They are at the fast end of the speed reading range, while studying is at the slow end. People who know how to skim and scan are flexible readers. They read according to their purpose and get the information they need quickly without wasting time. They do not read everything which is what increases their reading speed.
