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 77 students took test 1 Multiple Choice 53 students earned 35 or more points for those 53 the average was 43.6 (72.7%) Problems 60 students earned 24 or more points for those 60 the average was 42.4 (65.2%) 2nd test 76 students took test 2 Multiple Choice 58 students earned 30 or more points for those 58 the average was 41.4 (69.0%) Problems 54 students earned 30 or more points for those 54 the average was 43.6 (67.1%) 3rd test 69 students took test 3 Multiple Choice 46 students earned 30 or more points for those 46 the average was 40.7 (67.8%) Problems 51 students earned 21 or more points for those 51 the average was 40.1 (61.7%) 4th test 67 students took test 4 Multiple Choice 52 students earned 25 or more points for those 52 the average was 35.7 (59.5%) Problems 43 students earned 20 or more points for those 43 the average was 36.4 (55.9%) Overall averages 67 students took all four tests for these 67 students the final HW average is 20.7 points (82.9% of 25) the final test average is 47.0 points (62.6% of 75) and the overall average is 67.7 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 67 students. With this overall average the final grade scale is 50.7 - 60.6 D 60.7 - 73.6 C 73.7 - 84.6 B with below 50.7 as E and above 84.6 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 48.8, the lowest D is 50.7, the the highest D is 59.9, the lowest C is 60.8, the highest C is 69.8, the lowest B is 74.1, the highest B is 83.8, and the lowest A is 85.1. The smallest gap is 0.9 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 10 and 11 AM Monday July 6. After that time any change of grade requires a change of grade form.
