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 69 students took test 1 Multiple Choice 60 students earned 25 or more points for those 60 the average was 41.4 (69%) Problems 52 students earned 26 or more points for those 52 the average was 50.4 (77.5%) 2nd test 68 students took test 2 Multiple Choice 57 students earned 25 or more points for those 57 the average was 37.1 (61.9%) Problems 59 students earned 26 or more points for those 59 the average was 45.9 (70.7%) 3rd test 65 students took test 3 Multiple Choice 61 students earned 25 or more points for those 61 the average was 39.5 (65.8%) Problems 46 students earned 26 or more points for those 46 the average was 44.7 (68.7%) 4th test 63 students took test 4 Multiple Choice 46 students earned 25 or more points for those 46 the average was 34.0 (56.7%) Problems 44 students earned 26 or more points for those 44 the average was 40.7 (62.6%) Overall averages 63 students took all four tests for these 63 students the final HW average is 23.1 points (92.3% of 25) the final test average is 49.5 points (66% of 75) and the overall average is 72.6 points With this overall average the final grade scale is 55.6 - 66.1 D 66.1 - 76.6 C 76.6 - 87.1 B with below 55.6 as E and above 87.1 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 54.9, the highest D is 65.3, the highest C is 75.3, and the highest B is 86.2. The smallest gap is 0.7 points. Grades were assigned strictly based on this scale. Here is the grade distribution for those 63 students:
