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 96 students took test 1 Multiple Choice (now corrected) 73 students earned 25 or more points for those 73 the average was 38.9 (64.8%) Problems 71 students earned 32 or more points for those 71 the average was 48.5 (74.6%) multiple choice grades problem grades 2nd test 91 students took test 2 Multiple Choice 71 students earned 30 or more points for those 71 the average was 41.8 (69.7%) Problems 69 students earned 27 or more points for those 69 the average was 41.9 (64.5%) multiple choice grades problem grades 3rd test 78 students took test 3 Multiple Choice 66 students earned 30 or more points for those 66 the average was 39.5 (65.8%) Problems 59 students earned 31 or more points for those 59 the average was 43.3 (66.6%) multiple choice grades problem grades 4th test 78 students took test 4 Multiple Choice 60 students earned 35 or more points for those 60 the average was 45.1 (75.2%) Problems 58 students earned 19 or more points for those 58 the average was 32.9 (50.6%) multiple choice grades problem grades Overall averages 76 students took all four tests for these 76 students the final HW average is 22.6 points (90.4% of 25) the final test average is 50.1 points (66.8% of 75) and the overall average is 72.7 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 76 students. With this final average, the final grade scale is 56.2 - 66.1 D 66.2 - 78.5 C 78.6 - 88.5 B with below 56.2 as E and above 88.6 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 55.2, the lowest D is 56.3, the the highest D is 65.4, the lowest C is 66.2, the highest C is 76.3, the lowest B is 78.7, the highest B is 88.0, and the lowest A is 88.6. The smallest gap is 0.6 points between B and A. 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 19 or Monday July 2. After that time any change of grade requires a change of grade form.
