NOTE: In reporting the averages from the test we drop the lowest scores. This is because 25% (1 out of 4) 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.

FINAL AVERAGE 120 students took 3 or more MC parts, and 3 or more free response parts, plus the final exam, and had more than 715 HW points. For those 120 here are the averages: % points HW 84.00 6.72 RECITATION 78.90 5.52 (quiz+exercises) TP 89.20 4.46 test 57.35 34.41 exam 50.63 10.13 _________________________________ overall 61.24 <-- final average The final grade scale was primarily determined by the large gaps in the grade distribution. Here is that final grade scale. 38.4 - 47.0 D 47.1 - 62.2 C (above 60.8 is C+) 62.3 - 74.8 B (below 64.2 is B-, above 72.0 is B+) above 74.9 A (below 79.0 is A-, above 91.8 is A+) Letter grades were assigned strictly according to this scale. The highest E is 36.6, the lowest D is 38.5; the highest D is 44.7, the lowest C is 47.1; the highest C is 61.3, the lowest B is 62.3; the highest B is 74.1, and the lowest A is 74.9. The smallest gap between levels is 0.8 points between B to A. If you find a significant error in your recorded grades, the best time to see me is before NOON MON Dec 20th. After that time any change will require 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 120 students who took three or more MC and free-response test parts plus the final exam and had more than 715 HW points.
