Notes:

  • There were 77 students in the class, plus 3 no-shows.  The latter 3 were not included in the average.
  • The HW3 statistics above include the 5-point scaling I previously mentioned: that is, anyone who did HW3 got 5 points added to their HW3 grade automatically.
  • After some statistical crunching, I found that the final exams of the first and second groups were approximately 2 points apart; therefore, if you took the second (i.e., on the 16th) final, you got two "free" points for calibration purposes; they are included in the above numbers.  (The individual averages were not the same, but neither were the averages of students taking each exam, so they're not particularly useful.)
  • The bonus was added after the grade letter cutoffs were assigned.
  • If you're curious how I computed your grade, parse this Java function using your Courseworks numbers:
int computeTotalPoints() {
  int result = HW1+HW2+HW3+Midterm+HW4+HW5+HW6+Final;
  if(HW3 > 0) result += 5;
  if(FinalDate == 16) result += 2;
  result += MidtermBonus+HW4Bonus+HW5Bonus+
    HW6Bonus+FinalBonus;
  return result;
}
