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. These posted averages are not used in any way in calculating the final class average. GBA 1st test 41 students took test 1 MC 42 students took test 1 Lecture Quiz Multiple Choice 35 students answered 5 or more questions correctly for those 35 the average was 7.37/12 (61.4%) Lecture Quiz 32 students earned 10 or more points for those 33 the average was 24.6/40 (61.5%) multiple choice grades problem grades 2nd test 41 students took test 2 MC 41 students took test 2 Lecture Quiz Multiple Choice 31 students answered 5 or more questions correctly for those 31 the average was 7.32/12 (61.0%) Problems 31 students earned 11 or more points for those 31 the average was 25.3/40 (63.3%) multiple choice grades problem grades 3rd test 40 students took test 3 MC 40 students took test 3 Lecture Quiz Multiple Choice 29 students answered 5 or more questions correctly for those 29 the average was 7.79/12 (64.9%) Problems 29 students earned 11 or more points for those 29 the average was 20.8/40 (52.0%) multiple choice grades problem grades 4th test 38 students took test 4 MC 38 students took test 4 Lecture Quiz Multiple Choice 22 students answered 4 or more questions correctly for those 22 the average was 6.64/12 (55.3%) Problems 25 students earned 10 or more points for those 25 the average was 22.4/40 (56.0%) multiple choice grades problem grades Overall averages 37 students took three or more tests (including the fourth test) and had at least 1000 Sapling HW points for these 37 students the final TP average is 4.35 points (87.0% of 5 points) the final HW average is 6.83 points (85.4% of 8 points) the final quiz average is 5.33 points (76.1% of 7 points) the final test average is 44.58 points (55.73% of 80 points) the overall average is 61.1 points Note that the overall average includes all students who took three or more tests (including the fourth test) and who had at least 1000 HW points. 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 45 students. With this final average, the final grade scale is 36.1 - 43.3 D 43.4 - 62.7 C (above 58.5 is C+) 62.8 - 77.0 B (below 65.9 is B-, above 73.4 is B+) 77.1 and up A (below 79.3 is A-, above 92.1 is A+) with below 36.1 as E. The final scale was selected so as to find gaps in the distribution. With the scale as given above the highest E is 31.7, the lowest D is 36.1, the highest D is 41.3, the lowest C is 43.4, the highest C is 58.6, the lowest B is 62.9, the highest B is 73.6, and the lowest A is 77.2. The smallest gap is 2.1 points between D and C. Grades were assigned strictly based on this scale.
