Class participation: The numbers in the spreadsheet are the points I had recorded for you (including in-class team presentations), plus half a point for every time you signed the attendance sheet. To that I added 5 points to bring the base to 40 (but it was possible to get more); median = 35.
Final: Scores in the spreadsheet are raw. In the curve I compressed the scores slightly: multiplied by 0.79 and added 47 to raise the top score (194) to 200 and the median (156) to 170.
