Above, the points are computed as follows.

  1. First, all homework scores are summed, then multiplied by 100/104 so that the maximum can be 100 points; then multiplied by 0.45 so that the weight is 45% as specified in the course syllabus.
  2. Second, all quiz scores are summed, then multiplied by 100/60, so that the maximum can be 100 points; then multiplied by 0.15 because quizzes contribute 15% of the final score.
  3. Third, the exam scores are summed, then divided by 2, so that the maximum can be 100 points; then multiplied by 0.4 because the examinations have 40% weight in the total.
  4. Then the three terms above are added together and rounded to the nearest integer to give the points.
  5. The distribution is made by sorting the resulting scores for each section.

Scores greater than 82 are in the A-range, scores below 63 are in the C-range, though near the borders of the groupings, +/- modifiers to the grades may be assigned.

Note: to doublecheck the scoring, I put percentages for each event (homework, quiz, etc) in ICON, and had it compute scores. I did notice some small difference in the numbers, but nothing that would alter any of the letter grades.
