Purpose of Key Points

After we read or study a chapter, we have to identify key points in such a manner that if we think of a key point another 10 sentences associated with this key point should come out of us. One of the ideas is that brain stores every thing that we are reading or hearing, but a retrieval mechanism has to be put in place by us. Hence by attaching key points to some chunks of information and thinking about those key points more frequently will be a mechanism to tap knowledge that we are acquiring over a period of time in various subjects.
