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 100 students took test 1 Multiple Choice 74 students earned 25 or more points for those 74 the average was 35.4 (59.0%) Problems 76 students earned 24 or more points for those 76 the average was 42.6 (65.5%) multiple choice grades problem grades 2nd test 94 students took test 2 Multiple Choice 67 students earned 30 or more points for those 67 the average was 39.6 (66.0%) Problems 70 students earned 25 or more points for those 70 the average was 41.4 (63.7%) multiple choice grades problem grades 3rd test 93 students took test 3 Multiple Choice 65 students earned 25 or more points for those 65 the average was 33.0 (55.0%) Problems 69 students earned 22 or more points for those 55 the average was 36.2 (55.7%) multiple choice grades problem grades 4th test 89 students took test 4 Multiple Choice 66 students earned 25 or more points for those 66 the average was 37.3 (62.2%) Problems 52 students earned 21 or more points for those 52 the average was 38.0 (58.5%) multiple choice grades problem grades Overall averages 87 students took all four tests and had at least 90 homework points for these 87 students the final HW average is 8.2 points the final quiz average is 7.7 points the final test average is 57.6% (46.1 points) and the overall average is 62.0 points Note that the overall average includes all students who took four tests. The test average is computed by dropping the lowest MC section and the lowest problem section for each student (except one section of test 4 must be kept), computing each student's average, and then computing a global average for all 87 students. With this final average, the final grade scale is 42.8 - 53.0 D 53.1 - 65.6 C 65.7 - 75.6 B with below 42.8 as E and above 75.6 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 38.3, the lowest D is 42.8, the the highest D is 52.3, the lowest C is 53.1, the highest C is 64.7, the lowest B is 65.7, the highest B is 73.8, and the lowest A is 75.7. The smallest gap is 0.8 points between D and C. 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, please contact me or your TA.
