Calculating the final score

and

Letter Grade ranges

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

 to remind yourself of the weightings. Proper weighting of each component required normalization.

Here's how it was done:

1. Exams 1 & 2:  Muliply your Exam 1 score x 25/19 [= 1.32] & your Exam 2 score x 25/18 [= 1.39].  This normalizes each 

to its 25-point basis.   Add these two numbers together.

2. Final exam:

Note that one question [the 'vodka shot-glass'] was dropped, reducing the number of questions and the maximum possible 

raw score to 15.  Multiply your score [posted on your WebAssign page] by 1.67 to normalize it to the 25-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 182 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 74 points = 37 questions @ 2 points each. The lowest 10% were to be dropped, but 10% = 3.7 questions, so we dropped your lowest-scoring four (4) questions. Maximum points (adjusted) = 66.

Your adjusted score was then divided by 13.2 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 Grade Ranges based on final scores are as follows:

   A: 101 points and up;     A-: 98 - 100

   B+: 94 - 97;     B: 87 - 93;     B-: 84 - 86

   C+: 80 - 83;    C: 65 - 79;     C-: 60 - 64

   D: 46 - 59

   E: below 46

Y'all were one of my best Summer classes — all good wishes to each of you, and best of luck for your futures!
