5/10/13: FINAL GRADES POSTED

1. All work has now been graded.

2. The mean score on the Final Exam was 264/326 (81%).

3. There were 896 points possible on the three examinations, 25 points possible on the Constellation Quiz ("CQ"), and 80 nominal points possible on the in-class Puzzlahs ("PZ"), for a maximum possible nominal score of 1001.

4. Puzzlah scores were adjusted as follows. If your accumulated Puzzlah score during the semester is P, then the final recorded score (PZ) is computed as follows:
   • If P is 80 or below, then PZ = P
     
   • If P is above 80, then PZ = 80 + 0.5*(P-80) and rounded up.

   • The average PZ score was 84 points.

5. If you did any of the optional laboratories, then you received extra credit (labeled "XC" on the PostEm list) equal to the sum of the points achieved on the labs.

6. "TOT" is the combined score on all your work. It equals M1+M2+FX+PZ+CQ+XC. The mean TOT score was 861 points. Maximum and minimum TOT scores were 1023 and 506, respectively.

7. The final letter grades are CURVED, as explained on the syllabus. The grade breaks for A-, B-, and C- were all adjusted downward from the guaranteed values announced at the beginning of the semester.

8. You may look over your final exams in my office, but I am required to keep the papers.

Have a great summer! ---- R. W. O'Connell
