Above, the points are computed as follows.

- 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.
- 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.
- 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.
- Then the three terms above are added together
and rounded to the nearest integer to give the
points.
- 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.
