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. These posted test averages are not used in any way in computing the final overall class average.

With this predicted average a possible breakdown of grades would be: 49.2 - 59.7 D 59.8 - 70.7 C 70.8 - 81.3 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 123 students who had taken four or more tests and had more than 600 HW points, 122 took the final exam. One student who had no chance to pass also took the final. For the 123 students who took the final, the final exam average is 23.8 out of 40, or 59.5%. exam grades FINAL AVERAGE (Some mistakes were found in the initial TA reports; there may still be some more small changes. GBA) 122 students took 4 or more tests plus the final exam and had more than 600 HW points. For those 122 here are the averages: % points HW 88.05 7.04 QUIZ 76.46 5.35 PRS 89.92 4.50 test 59.95 35.97 (some corrections were made to the test 5 scores) exam 59.63 11.93 _________________________________ overall 64.8 <-- final average The final grade scale is a compromise between finding large gaps in the grade distribution and staying reasonably close to the predicted scale. Here is the final scale: 45.6 - 57.3 D 57.4 - 69.8 C (above 66.9 is C+) 69.9 - 79.0 B (below 74 is B-, above 77 is B+) above 79.0 A (below 83 is A-, above 90 is A+) Letter grades were assigned strictly according to this scale. The highest E is 41.5, the lowest D is 45.6; the highest D is 56.7, the lowest C is 57.4; the highest C is 69.2, the lowest B is 69.9; the highest B is 78.4, and the lowest A is 79.1. The smallest gap between levels is 0.7 points between D to C, between C to B, and between A and B. 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 before May 26th. I will be away from campus from May 27th to June 25th. At this point any change requires that we fill out 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 122 students who took four or more tests plus the final exam.
