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 179 students took test 1 35 made below 55 144 scored 55 or more for those 144 the average was 78.4 test 1 grades 2nd test 175 students took test 2 37 made below 44 138 scored 44 or more for those 138 the average was 67.2 test 2 grades 3rd test 175 students took test 3 34 made below 38 141 scored 38 or more for those 141 the average was 57.1 test 3 grades 4th test 139 students took test 4 27 made below 47 112 scored 47 or more for those 112 the average was 68.1 test 4 grades 5th test 128 students took test 5 26 made below 23 102 scored 23 or more for those 102 the average was 48.2 test 5 grades Overall Pre-Exam Average Note: Some errors were found in the reported averages for five sections. These corrections were put in on Mon 5/07 at 11 PM. 142 students have taken four or more tests and have more than 100 HW points. For these 142 students, the overall averages are test 64.1 (multiply by 0.6 to get # of points) HW 8.4 QUIZ 9.1 ________________________ overall 56.0 points out of 80 possible pre-exam points or 70.0% <-- Pre-Exam Average Estimating an average score of 14.0 (70%) on the final exam results in a predicted final average of 70.0 points. With this final average, a possible final grade scale would be 54.0 - 64.5 D 64.5 - 75.5 C 75.5 - 86.0 B The true final grade scale depends on overall class exam performance. FINAL EXAM Of the 142 students who had taken four or more tests and had more than 100 HW points, 132 took the final exam. For those 132 students the final exam average is 25.9 out of 39, or 66.4%. (We had to throw out one question) final exam grades FINAL AVERAGE 132 students took 4 or more tests plus the final exam for those 132 here are the averages: HW 8.5 (out of 10) quiz 9.3 (out of 10) test 65.2 (multiply by 0.6 to get #points) exam 25.9 (out of 39 - multiply by (20/39) to get #points) overall 70.2 (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: 54.0 - 64.5 D 64.6 - 75.5 C 75.6 - 86.1 B Letter grades were assigned strictly according to this scale. The highest E is 53.3, the lowest D is 54.1; the highest D is 63.9, the lowest C is 64.7; the highest C is 75.2, the lowest B is 76.5; the highest B is 85.6, and the lowest A is 86.3. 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 132 students who took four or more tests plus the final exam.
