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 59 students took test 1 Multiple Choice 45 students earned 20 or more points for those 45 the average was 31.3 (52.2%) Problems 42 students earned 21 or more points for those 42 the average was 39.1 (60.2%) multiple choice grades problem grades 2nd test 55 students took test 2 Multiple Choice 40 students earned 25 or more points for those 40 the average was 40.1 (66.8%) Problems 32 students earned 20 or more points for those 32 the average was 33.2 (51.1%) multiple choice grades problem grades 3rd test 50 students took test 3 Multiple Choice 36 students earned 25 or more points for those 36 the average was 33.2 (55.3%) Problems 67 students earned 24 or more points for those 67 the average was 32.6 (50.2%) multiple choice grades problem grades 4th test 47 students took test 4 Multiple Choice 38 students earned 20 or more points for those 38 the average was 31.7 (52.8%) Problems 36 students earned 21 or more points for those 36 the average was 35.4 (54.5%) multiple choice grades problem grades Overall averages 47 students took three or more tests (including the fourth test) and had at least 90 homework points for these 47 students the final PRS average is 4.12 points (out of 5) the final HW average is 5.87 points (out of 8) the final quiz average is 4.82 points (out of 7) the final test average is 42.72 points (53.4% of 80) and the overall average is 57.5 points Note that the overall average includes all students who took three or more tests (including the fourth test) and who had at least 90 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 47 students. With this final average, the final grade scale is 40.7 - 50.6 D 50.7 - 61.8 C (no C+'s this year) 61.9 - 74.3 B (below 66.0 is B-, no B+'s this year) 74.4 and up A (below 76.4 is A-, no A+'s this year) with below 40.7 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 38.9, the lowest D is 40.7, the the highest D is 49.4, the lowest C is 50.7, the highest C is 58.3, the lowest B is 61.9, the highest B is 69.9, and the lowest A is 74.4. The smallest gap is 1.3 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.
