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.

Here is that final grade scale. 41.2 - 49.4 D 49.5 - 65.7 C (above 62.6 is C+) 65.8 - 77.7 B (below 67.1 is B-, above 75.4 is B+) above 77.8 A (below 79.5 is A-, above 90.5 is A+) Letter grades were assigned strictly according to this scale. The highest E is 40.2, the lowest D is 42.1; the highest D is 48.0, the lowest C is 49.5; the highest C is 65.0, the lowest B is 65.8; the highest B is 76.3, and the lowest A is 77.9. The smallest gap between levels is 0.8 points between C to B. If you find a significant error in your recorded grades, the best time to see me is before NOON FRI Dec 18th. 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.
