USEFUL HARD COPY
In class you will take notes of the information that is given and what occurs during the class. The main reason for taking notes is to help you concentrate, and later to remember the important ideas and procedures that were used. Notes are useful study tools and can help you organise your understanding of the concepts. Most other people in the class will take notes and you won't want to be left out.
Sometimes you won't want to take notes. In lectures, a great deal of theory will be displayed and discussed. You may have a course outline and receive a complete set of notes for the course. Sometimes lecturers hand out copies of their overhead slides in every lecture. So you may feel that there is no need for you to take your own notes. You may feel it's better to listen carefully, rather than writing just for the sake of it. But make sure you do not simply sleep!
