Read early in the morning. When you are awake and alert, your reading comprehension is far greater than when you are tired. Morning is also a good time to highlight information that you find important.
Read for short periods of time. You don't have to sit and read 20 chapters all at once. Read a chapter, or a portion of a chapter, at each sitting. Reading for 35 to 40 minutes will help to make the time you spend more effective than would the daunting task of sitting to read for hours.
Read somewhere quiet. Don't sit in front of the TV, at a coffee shop or in common areas in the dorm while you read. Find a quiet location so that you can really focus on the material.
Monitor how effective your reading is. Stop every once in awhile and ask yourself what you have learned. If you have difficulty answering the question, you will know that you have to go back and read the material again.
Broaden your knowledge. Reading about a variety of topics will help when it comes to information that you may not have known otherwise. It can save you time if you already have a knowledge base rather than having to stop your reading to research further information.
