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 114 students took test 1 25 made below 26 89 scored 26 or more for those 89 the average was 49.4 test 1 grades 2nd test 114 students took test 2 24 made below 39 90 scored 39 or more for those 90 the average was 59.1 test 2 grades 3rd test 95 students took test 3 21 made below 38 74 scored 38 or more for those 74 the average was 65.5 test 3 grades 4th test 88 students took test 4 17 made below 39 71 scored 39 or more for those 71 the average was 61.6 test 4 grades 5th test 80 students took test 5 17 made below 20 63 scored 20 or more for those 63 the average was 41.8 test 5 grades You may also compare with Fall 2001 grades. Overall Pre-Exam Average 86 students have taken four or more tests and have more than 100 HW points. For these 86 students, the overall averages are test 55.4 (multiply by 0.6 to get # of points) HW 7.3 QUIZ 6.6 ________________________ overall 47.1 points out of 80 possible pre-exam points or 58.9% <-- Pre-Exam Average Assuming an average of 65 on the final, or 13 out of 20 points, results in a predicted overall average of 60.1. With this predicted average a possible breakdown of grades would be: 44.7 - 54.6 D 54.7 - 65.6 C 65.7 - 75.6 B You should figure your pre-exam total then figure how many exam points (out of 20 possible) you need to get the grade that you want. Remember that the true final grade scale ultimately depends on overall class exam performance. FINAL EXAM Of the 86 students who had taken four or more tests and had more than 100 HW points, 86 took the final exam. For those 86 students the final exam average is 24.3 out of 40, or 60.7%. FINAL AVERAGE 86 students took 4 or more tests plus the final exam for those 86 here are the averages: HW 7.3 (out of 10) quiz 6.6 (out of 10) test 55.4 (multiply by 0.6 to get #points) exam 24.3 (out of 40 - divide by 2 to get #points) overall 59.3 (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: 42.8 - 52.7 D 52.8 - 65.7 C 65.8 - 75.7 B Letter grades were assigned strictly according to this scale. The highest E is 41.7, the lowest D is 43.1; the highest D is 51.7, the lowest C is 52.8; the highest C is 65.1, the lowest B is 66.7; the highest B is 74.9, and the lowest A is 76.2. The smallest gap between levels is 1.1 points between D to C. 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 Tuesday afternoon or Thursday morning 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 86 students who took four or more tests plus the final exam.
