NOTE: In reporting the averages from the tests we drop the lowest scores. This is because the lowest of the three tests will be weighted half as much as the other two in the final averaging. This half-weighting is equivalent to dropping 1/6th (or 16.7%) of all test scores. 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. below 36.1 E 36.1 - 45.0 D 45.0 - 60.9 C (above 56.9 is C+) 60.9 - 73.3 B (below 62.1 is B-, above 68.6 is B+) above 73.3 A (below 75.5 is A-, above 91.8 is A+) Letter grades were assigned strictly according to this scale. The highest E is 34.7, the lowest D is 36.1; the highest D is 44.1, the lowest C is 45.0; the highest C is 60.2, the lowest B is 60.9; the highest B is 72.0, and the lowest A is 73.4. The smallest gap between levels is 0.7 points between C to B. You may also like to look at the Fall 2012 Class Averages.
