This preference uses the printed word as the most important way to convey and receive information. When revising for exams, normally, I tend to make notes by reading out of textbooks. I will separate the topics. For example, if revising for science, I would separate Biology, Chemistry and Physics. Then I would go over the notes and try to retain them, then say them to the people I am with to make sure I remember, then I would go through a exam paper and see what I know, and what I don't.
Here is a small list of ways to do this.
Read your notes (silently) again and again.
Rewrite the ideas and principles into other words.
