NOTE: In reporting the averages from the test we drop the lowest scores. This is because 16.7% (1 out of 6) 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 40 students took test 1 Multiple Choice 31 students earned 20 or more points for those 31 the average was 34.6 (57.7%) Problems 21 students earned 16 or more points for those 21 the average was 26.9 (44.8%) multiple choice grades problem grades 2nd test 39 students took test 2 Multiple Choice 28 students earned 22 or more points for those 28 the average was 33.0 (55.0%) Problems 28 students earned 15 or more points for those 28 the average was 28.36 (47.3%) multiple choice grades problem grades 3rd test Because one half of one test can be dropped, many students choose not to study as seriously for Test 3 as they study for Tests 1 and 2. As a result, we report the averages only for those students who keep the relevant half of Test 3. GBA 35 students took test 3 Multiple Choice 24 students did not drop Test 3 MC for those 24 the average was 25.0 (41.7%) Problems 29 students did not drop Test 3 Problems for those 29 the average was 24.5 (40.8%) multiple choice grades problem grades Overall averages 35 students took three tests and had at least 112 homework points for these 35 students the final CPS average is 4.26 points (out of 5) the final HW average is 6.77 points (out of 8) the final quiz average is 5.20 points (out of 7) the final test average is 35.30 points (44.12% of 80) the overall average is 51.5 points Note that the overall average includes all students who took three tests and who had at least 112 HW points. The test average is computed by dropping the lowest MC or problem section for each student, computing each student's average, and then computing a global average for all 35 students. With this final average, the final grade scale is 30.2 - 41.3 D 41.3 - 51.6 C (above 48.6 is C+) 51.7 - 66.8 B (below 55.6 is B-, above 64.0 is B+) 66.9 and up A (below 69.7 is A-, above 88.2 is A+) with below 30.2 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 26.5, the lowest D is 30.2, the highest D is 37.7, the lowest C is 41.3, the highest C is 50.9, the lowest B is 51.7, the highest B is 64.1, and the lowest A is 66.9. The smallest gap is 0.8 points between C and B. Grades were assigned strictly based on this scale.
