Grading Scales
Dr. Stockrahm has given me your homework grades and Test 1 grade. As he announced in class, for your Test 2 grade to be recorded you must talk to him in his office - this is whether or not you are expecting extra points. If you do not talk to him about test 2, you will get a zero for that exam. He will give me those grades before the end of the semester.
Dr. Stockrahm had originally set up the grading system as follows. Assuming that Dr. Stockrahm's homework total would have been on the order of 50 points (which is reasonably close to what it looked like as of Oct. 30), his weights would have been approximately what I have listed in the table below.

Stockrahm's Grade |
|||||
| Homework | 1 point each problem graded | approx. 10% | Lowest A | 90% | |
| Exam 1 | 100 points | approx. 15% | Lowest B | 80% | |
| Exam 2 | 100 points | approx. 15% | Lowest C | 70% | |
| Exam 3 | 100 points | approx. 15% | Lowest D | 60% | |
| Exam 4 | 100 points | approx. 15% | F | <60% | |
| Final | 200 points | approx. 30% | |||
I don't like to be constrained as to how many homework problems I grade or to just one point per problem - I prefer to have each problem be worth enough points that I can give a reasonable level of partial credit on homework as well as on exams. Therefore, I don't evaluate course grades based on total points but on weighting scales. I also like to encourage you to do the homework more, and therefore give it a higher weight than Dr. Stockrahm had. So I will modify the grading weights to be the following:
|
Hill's Grading Weights |
|
| Labs/Homework | 20% |
| Exam 1 | 15% |
| Exam 2 | 15% |
| Exam 3 | 15% |
| Exam 4 | 15% |
| Final | 20% |
Note: For the lab/homework grade, only the top 14 labs/homeworks will be counted (out of approximately 18).
I scale each lab assignment to ten-points. To convert Dr. Stockrahm's grades to a ten point scale, do the following:
For a homework assignment worth 5 points: Multiply your grade by 2.
For a homework assignment worth 3 points: A score of 0/3 will be 0/10. A score of 1/3 will be 4/10. A score of 2/3 will be 7/10. A score of 3/3 will be 10/10.
The homework grades from the first part of the course include seven 5-point assignments and one 3-point assignment, for eight assignments total. I expect to give approximately 10 lab assignments in addition to these prior homework grades. Any 14 of the the 18 assignments can be kept, so good assignments from Dr. Stockrahm will still count, and bad or missed assignments from him can be thrown out if you do the labs.
The grading scale for letter grades will be what I have below, which matches Dr. Stockrahm's statement but with the +/- categories spelled out.
