Calculating your final score

Your letter-grade-determining final score [120 points, max.] has 5 components —see the syllabus

if you need reminding! Their proper weighting required normalization.

Here's how it was done:

1. Exams 1 & 2: Add your scores (20 points, max, each) and multiply the result by 1.25. This normalizes the total to the 120-point grading basis.

2. Final exam: multiply this score [posted on your WebAssign page] by 1.67 to normalize it to the 120-point basis.

3. Add the results you got in Steps 1 and 2, above, giving you a number no higher than 75.

4. To this number add your discussion/recitation score (get from your section instructor; maximum 25 points). Your total should now be 100 or less.

5. WebAssign: there were 11 assignments, totalling 183 points. WebAssign posting totals included your Exams 1 & 2 scores; be sure to remove them if you are using WA totals to do your own calculation. Your lowest-scoring assignment was dropped, leaving a maximum of 172 points.

The result was divided by 11.46 [172/11.46 = 15] to normalize it to the 15-point maximum weighting.

6. h-itt (in-lecture/'clicker' quizzes): there were 14 quizzes totalling 66 points = 33 questions @ 2 points each. The lowest 10% were to be dropped, but 10% = 3.3 questions, so we dropped your lowest-scoring four (4) questions. Maximum points =58.

Your adjusted score was then divided by 11.6 to normalize to the maximum weighting of 5 points.

7. The total of the above 5 numbers should be a number less than 120. This is your final score.

Letter Grades are being calculated. They will be assigned according to a 'curve' very similar to that published in the Syllabus. The curve may move a point or two, depending on the overall class average (not yet determined) but don't count on it.

Letter grade ranges [the 'curve'] will be appended to this posting [below] as soon as they are ready — hopefully by Sunday. Notice of this will appear in the Announcements.
