NOTE: In reporting the averages from the test we drop the lowest scores. This is because 25% (2 out of 8) 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. GBA 1st test 92 students took test 1 Multiple Choice 70 students earned 30 or more points for those 70 the average was 41.3 (68.8%) Problems 71 students earned 41 or more points for those 71 the average was 53.8 (82.8%) 2nd test 85 students took test 2 Multiple Choice 66 students earned 30 or more points for those 66 the average was 42.1 (70.2%) Problems 63 students earned 35 or more points for those 63 the average was 45.0 (69.2%) 3rd test 82 students took test 3 Multiple Choice 58 students earned 30 or more points for those 58 the average was 37.3 (62.2%) Problems 62 students earned 31 or more points for those 62 the average was 45.6 (70.2%) 4th test 80 students took test 4 Multiple Choice 64 students earned 25 or more points for those 64 the average was 35.9 (59.8%) Problems 59 students earned 18 or more points for those 59 the average was 33.2 (51.1%) Overall averages 78 students took all four tests for these 78 students the final HW average is 21.0 points (83.9% of 25) the final test average is 49.7 points (66.3% of 75) and the overall average is 70.7 points Note that the overall average includes all students who took four tests. The test average is computed by dropping the two lowest test 'halves' for each student, computing each student's average, and then computing a global average for all 78 students. With this final average, the final grade scale is 55.7 - 65.4 D 65.5 - 75.6 C 75.7 - 84.9 B with below 55.7 as E and above 84.9 as A. The final scale was selected so as to find gaps in the distribution. With the scale as given above the highest E is 54.0, the lowest D is 57.1, the the highest D is 64.1, the lowest C is 65.5, the highest C is 75.0, the lowest B is 77.2, the highest B is 83.8, and the lowest A is 85.0. The smallest gap is 1.2 points. Grades were assigned strictly based on this scale. 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 between 11 and 12 AM Friday June 30 or Monday July 3. After that time any change of grade requires a change of grade form.
