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 109 students took test 1 Multiple Choice 82 students earned 20 or more points for those 82 the average was 32.6 (54.3%) Problems 85 students earned 33 or more points for those 85 the average was 49.8 (76.6%) multiple choice grades problem grades 2nd test 107 students took test 2 Multiple Choice 82 students earned 20 or more points for those 82 the average was 30.8 (51.3%) Problems 82 students earned 27 or more points for those 82 the average was 44.2 (68.0%) multiple choice grades problem grades 3rd test 103 students took test 3 Multiple Choice 76 students earned 30 or more points for those 76 the average was 40.1 (66.8%) Problems 78 students earned 26 or more points for those 78 the average was 40.8 (62.8%) multiple choice grades problem grades 4th test 100 students took test 4 Multiple Choice 72 students earned 25 or more points for those 72 the average was 33.5 (55.8%) Problems 75 students earned 19 or more points for those 75 the average was 34.1 (58.3%) multiple choice grades problem grades Overall averages 100 students took all four tests and had more than 90 HW points for these 100 students the final HW average is 8.4 points the final Quiz average is 8.3 points the final test average is 59.7% (multiply by .8 to get number of points) and the overall average is 64.5 points Note that the overall average includes all students who took four tests. The test average is computed by dropping the lowest MC and the lowest Problems section for each student, computing each student's average, and then computing a global average for all 100 students. Also, adjustments were made to the HW and Quiz averages to account for different grading practices for the five TAs. With this final average, the final grade scale is 46.8 - 57.3 D 57.4 - 68.0 C 68.1 - 78.4 B with below 46.8 as E and above 78.4 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 44.4, the lowest D is 46.8, the the highest D is 56.5, the lowest C is 57.4, the highest C is 66.7, the lowest B is 68.1, the highest B is 78.0, and the lowest A is 78.5. The smallest gap is 0.5 points between A and B. Grades were assigned strictly based on this scale. Be sure to check your TA's computation of your final grade.
