  119 On this page, you can monitor the average progress of students for all recitations or
  120 by individual recitations. You can identify difficult problems by the percentage of students
  121 who have answered the problem correctly and/or by the average number of incorrect attempts
  122 per problem. All percentages and averages (except \% attempting) are based on the number of
  123 students who have attempted a set or problem, not on the total number of students in the recitation
  124 or course.  Note that 50\% correct on a partial credit question could mean all students got half
  125 credit or half the students got full credit and half got no credit.<p>
  126 The first two tables do not contain data from "excluded" recitations. Excluded recitations
  127 typically contain practices uses, T.A.'s, prof's etc.  Data for excluded recitations is displayed
  128 at the bottom of the page.
