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. Their skill lies in knowing what specific information to read and which method to use.

What Is Skimming?(I've talked in your class)

Skimming is one of the tools you can use to read more in less time.Skimming refers to looking only for the general or main ideas, and works best with non-fiction (or factual) material. With skimming, your overall understanding is reduced because you don’t read everything. You read only what is important to your purpose. Skimming takes place while reading and allows you to look for details in addition to the main ideas.

How to skim. Many people think that skimming is a haphazard process placing the eyes where ever they fall. However, to skim effectively, there has to be a structure but you don’t read everything. What you read is more important than what you leave out. So what material do you read and what material do you leave out?
