Strategy 2 | Knowing how deeply to study the material

Where you only need the shallowest knowledge of the subject, you can skim material. Here you read only chapter headings, introductions and summaries.

If you need a moderate level of information on a subject, then you can scan the text. Here you read the chapter introductions and summaries in detail. You may then speed read the contents of the chapters, picking out and understanding key words and concepts. At this level of looking at the document it is worth paying attention to diagrams and graphs.

Only when you need detailed knowledge of a subject is it worth studying the text. Here it is best to skim the material first to get an overview of the subject. This gives you an understanding of its structure, into which you can fit the detail gained from a full, receptive reading of the material. SQ3R is a good technique for getting a deep understanding of a text.
