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   

   78 students have taken four or more tests and have more
      than 650 HW points.  For these  78 students, the
      overall averages are (updated with reported numbers
      from all sections on TUE 5/8 at 10 AM)

                       %      points

        HW           75.9     6.07

        QUIZ         64.2     4.49

        PRS          72.0     3.60

        test         51.2    30.72

     overall                 44.88 points out of 80 possible 
                                           pre-exam points

                or   55.8%  <-- Pre-Exam Average

    Assuming an average of 65 on the final, or 13 out of
20 points, results in a predicted overall average of 57.9.
With this predicted average a possible breakdown of grades
would be:

                42.4 - 52.3   D
                52.4 - 63.3   C
                63.4 - 73.3   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.


      While 78 students had taken four or more tests and had 
      more than 650 HW points, 82 students took the final exam.  
      For the 78 students who took the final and had a chance
      to pass, the final exam average is 

                  17.4 out of 40, or 43.5%.

 (Some mistakes were found in the initial TA reports; also,
  adjustments were made to TA quiz averages to account for
  differing TA quiz grading practices.)

  78  students took 4 or more tests plus the final exam and
      had more than 650 HW points.

     For those 78 here are the averages:
                       %      points

        HW           77.20    6.18

        QUIZ         77.94    5.46

        PRS          72.20    3.61

        test         51.13   30.68 
        exam         43.43    8.69

     overall                 54.6  <-- final average

    The final grade scale was primarily determined by the
large gaps in the grade distribution.  Here is the final 

      38.8 - 49.9   D
      50.0 - 62.0   C  (above 59.6 is C+)
      62.1 - 69.5   B  (below 65 is B-, above 68.4 is B+)
      above 69.5    A  (below 72 is A-, above 82 is A+)

Letter grades were assigned strictly according to this
scale.  The highest E is 36.8, the lowest D is 38.8;  the
highest D is 48.3, the lowest C is 50.1;  the highest C
is 59.7, the lowest B is 62.6; the highest B is 68.6,
and the lowest A is 69.6.  The smallest gap between
levels is 1.0 points between B to A.

    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 Noon May 11th.  After that time any change will 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.
