conscientious job on the Mars and/or Jupiter labs, you can assume
that you received at least 75% of the credit possible.

semester except the final exam score.

5/08/14: FINAL GRADES POSTED
- All work has now been graded.
- The mean score on the Final Exam was 268/326 (82%).
- 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.
- 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 80 points. If you handed in Puzzlah
answers on paper, those were recorded under "AddPZ" and included in
your TOT score.

- If you did any of the optional laboratories, then you received
extra credit, listed under "Tel", "Mars", or "Jup".
- "TOT" is the combined score on all your work. It equals
M1+M2+FX+PZ+AddPZ+CQ+Tel+Mars+Jup. The mean TOT score was 856
points. Maximum and minimum TOT scores were 1007 and 599.
respectively.
- 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.
- 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
