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.

For these 78 students, the overall averages are (updated with reported numbers from all sections on TUE 5/8 at 10 AM) % points HW 75.9 6.07 QUIZ 64.2 4.49 PRS 72.0 3.60 test 51.2 30.72 _________________________________ overall 44.88 points out of 80 possible pre-exam points or 55.8% <-- Pre-Exam Average Assuming an average of 65 on the final, or 13 out of 20 points, results in a predicted overall average of 57.9. With this predicted average a possible breakdown of grades would be: 42.4 - 52.3 D 52.4 - 63.3 C 63.4 - 73.3 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 While 78 students had taken four or more tests and had more than 650 HW points, 82 students took the final exam. For the 78 students who took the final and had a chance to pass, the final exam average is 17.4 out of 40, or 43.5%. exam grades FINAL AVERAGE (Some mistakes were found in the initial TA reports; also, adjustments were made to TA quiz averages to account for differing TA quiz grading practices.) 78 students took 4 or more tests plus the final exam and had more than 650 HW points. For those 78 here are the averages: % points HW 77.20 6.18 QUIZ 77.94 5.46 PRS 72.20 3.61 test 51.13 30.68 exam 43.43 8.69 _________________________________ overall 54.6 <-- final average The final grade scale was primarily determined by the large gaps in the grade distribution. Here is the final scale: 38.8 - 49.9 D 50.0 - 62.0 C (above 59.6 is C+) 62.1 - 69.5 B (below 65 is B-, above 68.4 is B+) above 69.5 A (below 72 is A-, above 82 is A+) Letter grades were assigned strictly according to this scale. The highest E is 36.8, the lowest D is 38.8; the highest D is 48.3, the lowest C is 50.1; the highest C is 59.7, the lowest B is 62.6; the highest B is 68.6, and the lowest A is 69.6. The smallest gap between levels is 1.0 points between B to A. 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 Noon May 11th. After that time any change will 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 78 students who took four or more tests plus the final exam.
