NOTE:  In reporting the averages from the test we drop
       the lowest scores.  This is because 25% (1 out
       of 4) of all scores will eventually be dropped.
       In comparing your average with the class average
       you need to compare with an average which is
       representative of the final average.  Dropping
       the lowest scores before reporting the average
       is one way of ESTIMATING the effect of the final 
       drops.  These posted test averages are not used 
       in any way in computing the final overall class 
       average.  GBA

Overall Pre-Exam Average   

  96 students have taken three or more tests and have more
     than 600 HW points.  For these 96 students, the
     overall averages are

                     %     points

      PRS          83.54     4.18

      QUIZ         78.87     5.52

      HW           82.73     6.62

      test         60.06    36.04

   overall                  52.36  out of 80 possible pre-exam points

                       or   65.45%  <-- Predicted Pre-Exam Average

    Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 65.4
With this predicted average a POSSIBLE breakdown of grades
would be:

                49.9 - 59.9   D
                60.0 - 70.9   C
                71.0 - 81.0   B

You should figure your pre-exam total then figure how many
exam points (out of 20 possible) you need to get the grade
that you want.  Remember that the true final grade scale 
ultimately depends on overall class exam performance.  Also, 
the final grade scale will be selected so as to find gaps
in the final grade distribution.


     103 students took the final exam.  For those 103 students,
         the final exam average is 

            21.84 out of 40, or  54.61%.

       final exam grades


 98 students took 3 or more tests plus the final exam
    and had more than 600 HW points (the TAs had missed
    two students whose MP ID numbers did not agree with
    their posting IDs)

       for those 98 here are the averages:

                     %     points

      PRS          84.00    4.20 

      QUIZ         79.00    5.53 

      HW           82.25    6.58 

      test         60.15   36.09  

      EXAM         54.95   10.99 

   overall                 63.39  (out of 100) <== Final Average

The final grade scale was selected so as to find gaps
in the grade distribution.  Here is that final scale:

        43.7 - 54.6   D
        54.7 - 69.7   C   (above 66.3 is C+)
        69.8 - 80.4   B   (below 71.7 is B-, above 78.6 is B+)
        80.5 and up   A   (below 84.1 is A-, above 91.1 is A+)

Letter grades were assigned strictly according to this
scale.  The highest E is 42.4, the lowest D is 43.7;  the
highest D is 53.4, the lowest C is 54.7;  the highest C
is 68.8, the lowest B is 69.8;  the highest B is 78.7,
and the lowest A is 80.5.  The smallest gap between
levels is 1.0 points between C to B.

    Be sure to check your TA's computation of your final grade.
If you find a significant error the best time to see me is
Thursday May 12 between 2:00 - 4:00 PM.  After that time any 
change will require that we fill out a change-of-grade form.

who took four or more tests plus the final exam, and had
at least 600 HW points.
