NOTE: In reporting the averages from the test we drop the lowest scores. This is because 20% (1 out of 5) 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 143 students took test 1 28 made below 51 115 scored 51 or more for those 115 the average was 79.5 test 1 grades 2nd test 131 students took test 2 25 made below 45 106 scored 45 or more for those 106 the average was 69.3 test 2 grades 3rd test 125 students took test 3 25 made below 37 100 scored 37 or more for those 100 the average was 56.7 test 3 grades 4th test 114 students took test 4 23 made below 48 91 scored 48 or more for those 91 the average was 68.5 test 4 grades 5th test 107 students took test 5 22 made below 29 85 scored 29 or more for those 85 the average was 53.6 test 5 grades Overall Pre-Exam Average Note: Some errors were found in the reported averages for one section. These corrections were put in on Mon 5/07 at 11 PM. 114 students have taken four or more tests and have more than 100 HW points. For these 114 students, the overall averages are test 65.5 (multiply by 0.6 to get # of points) HW 7.5 QUIZ 8.1 ________________________ overall 54.9 points out of 80 possible pre-exam points or 68.7% <-- Pre-Exam Average Estimating an average score of 14 (70%) on the final exam results in a predicted final average of 68.9 points. With this final average, a possible final grade scale would be 52.9 - 63.4 D 63.4 - 74.4 C 74.4 - 84.9 B The true final grade scale depends on overall class exam performance. FINAL EXAM Of the 114 students who had taken four or more tests and had more than 100 HW points, 106 took the final exam. For those 106 students the final exam average is 26.4 out of 40, or 66%. final exam grades FINAL AVERAGE 106 students took 4 or more tests plus the final exam for those 106 here are the averages: HW 7.7 (out of 10) quiz 8.3 (out of 10) test 66.5 (multiply by 0.6 to get #points) exam 26.4 (out of 40 - divide by 2 to get #points) overall 69.1 (out of 100) <-- Final Average The final grade scale was selected so as to find gaps in the grade distribution. Here is that final scale: 52.9 - 63.4 D 63.5 - 74.4 C 74.5 - 84.4 B Letter grades were assigned strictly according to this scale. The highest E is 51.8, the lowest D is 53.1; the highest D is 62.9, the lowest C is 64.4; the highest C is 73.7, the lowest B is 75.5; the highest B is 83.9, and the lowest A is 84.6. The smallest gap between levels is 0.7 points between B to A. Be sure to check your TA's computation of your final grade. If you find a significant error the best time to see me is Thursday afternoon or Friday between 10:30 and 11:30 AM. After that time any change of grade requires a change of grade form. For information on how to figure your final grade see HOW TO FIGURE YOUR FINAL GRADE. Here is the final grade distribution for the 106 students who took four or more tests plus the final exam.
