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 52 students took test 1 Multiple Choice 37 students earned 25 or more points for those 37 the average was 41.9 (69.8%) Problems 39 students earned 19 or more points for those 39 the average was 40.6 (62.5%) multiple choice grades problem grades 2nd test 50 students took test 2 Multiple Choice 36 students earned 30 or more points for those 36 the average was 42.6 (71.0%) Problems 38 students earned 24 or more points for those 38 the average was 45.7 (70.3%) multiple choice grades problem grades 3rd test 49 students took test 3 Multiple Choice 35 students earned 30 or more points for those 35 the average was 44.4 (74.0%) Problems 37 students earned 20 or more points for those 37 the average was 37.2 (57.2%) multiple choice grades problem grades 4th test 42 students took test 4 Multiple Choice 27 students earned 25 or more points for those 27 the average was 35.7 (59.5%) Problems 30 students earned 15 or more points for those 30 the average was 36.3 (55.8%) multiple choice grades problem grades Overall averages 41 students took three or more tests (including the fourth test) and had at least 100 homework points for these 41 students the final PRS average is 4.35 points (out of 5) the final HW average is 7.02 points (out of 8) the final quiz average is 6.09 points (out of 7) the final test average is 49.70 points (62.13% of 80) the overall average is 67.2 points Note that the overall average includes all students who took three or more tests (including the fourth test) and who had at least 100 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 41 students. We figured the final grade scale based on a weighted average from the Summer 2002-2007 classes; this weighted average was 63.5 and was taken as the approximate middle C for the following grade scale: 44.3 - 54.5 D 54.6 - 66.9 C (above 64.6 is C+) 67.0 - 80.5 B (below 73.0 is B-, above 78.2 is B+) 80.6 and up A (below 83.9 is A-, above 91.9 is A+) with below 44.3 as E. The final scale was selected so as to find gaps in this year's distribution. With the scale as given above the highest E is 41.8, the lowest D is 44.3, the the highest D is 52.6, the lowest C is 54.6, the highest C is 65.4, the lowest B is 67.0, the highest B is 78.2, and the lowest A is 80.6. The smallest gap is 1.6 points between C and B. 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.
