   8     <p>The Use Password option is used to associate a
   9     &quot;access&quot; password with the exercise. There may be
  10     occasions when it is necessary to password protect an exercise. For
  11     example, an exercise may be used with several groups of students in a
  12     course and each group is set the exercise at different times. The access
  13     password is used to prevent the &quot;second&quot; group of students, say,
  14     from doing the exercise once the exercise has been opened up for the
  15     &quot;first&quot; group.</p>
