NOTE:  In reporting the averages from the test we drop
       the lowest scores.  This is because 20% (1 out
       of 5) 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   

  123 students have taken four or more tests and have more
      than 600 HW points.  For these 123 students, the
      overall averages are

                       %      points

        HW           87.5     7.00

        QUIZ         75.9     5.31

        PRS          89.4     4.47

        test         59.3    35.55

     overall                 52.33 points out of 80 possible 
                                           pre-exam points

                or   65.4%  <-- Pre-Exam Average

    Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 65.3.
With this predicted average a possible breakdown of grades
would be:

                49.2 - 59.7   D
                59.8 - 70.7   C
                70.8 - 81.3   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.


      Of the 123 students who had taken four or more tests and 
      had more than 600 HW points, 122 took the final exam.  One
      student who had no chance to pass also took the final.
      For the 123 students who took the final, the final exam 
      average is 

                  23.8 out of 40, or 59.5%.

 (Some mistakes were found in the initial TA reports; there
  may still be some more small changes. GBA)
 122 students took 4 or more tests plus the final exam and
     had more than 600 HW points.

     For those 122 here are the averages:
                       %      points

        HW           88.05    7.04

        QUIZ         76.46    5.35

        PRS          89.92    4.50

        test         59.95   35.97  (some corrections were made
                                     to the test 5 scores)
        exam         59.63   11.93

     overall                 64.8  <-- final average

    The final grade scale is a compromise between finding
large gaps in the grade distribution and staying reasonably
close to the predicted scale.  Here is the final scale:

      45.6 - 57.3   D
      57.4 - 69.8   C  (above 66.9 is C+)
      69.9 - 79.0   B  (below 74 is B-, above 77 is B+)
      above 79.0    A  (below 83 is A-, above 90 is A+)

Letter grades were assigned strictly according to this
scale.  The highest E is 41.5, the lowest D is 45.6;  the
highest D is 56.7, the lowest C is 57.4;  the highest C
is 69.2, the lowest B is 69.9;  the highest B is 78.4,
and the lowest A is 79.1.  The smallest gap between
levels is 0.7 points between D to C, between C to B,
and between A and 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
before May 26th.  I will be away from campus from May 27th to 
June 25th.  At this point any change requires that we fill out 
a change-of-grade form.  For information on how to figure your 
final grade see

who took four or more tests plus the final exam.
