Determining your current grade involves only computing weighted percentages.
Suppose we've had six homework assignments so far, and you've turned in five. We've had three quizzes and a midterm. Suppose your scores are as follows:
Homework | 43/48, 51/52, 0, 33/33, 62/64, and 36/43 | |
Quizzes | 27/30, 23/25, 20/20 | |
Midterm 1 | 81/100 |
Here's how I would compute your current grade:
First I convert each score to a percentage:
Homework | 89.6, 98.0, 0.0, 100.0, 96.9, and 83.7 | |
Quizzes | 90, 92, 100 | |
Midterm 1 | 81 |
Then I take the average in each category. In Math 76, the two lowest homework scores and the two lowest quiz scores are dropped from the final grade. I compute the current grade both with and without the drops, for illustration purposes:
With two lowest homework scores and two lowest quiz scores dropped: | ||||
---|---|---|---|---|
Homework | (89.6 + 98.0 + |
= | 96.1% | |
Quizzes | ( |
= | 100% | |
Midterm 1 | = | 81% | ||
With no dropped scores: | ||||
Homework | (89.6 + 98.0 + 0.0 + 100.0 + 96.9 + 83.7) / 6 | = | 78.0% | |
Quizzes | (90 + 92 + 100) / 3 | = | 94% | |
Midterm 1 | = | 81% |
In Math 76, homework, quizzes, midterms and final each count for 19% of the final grade. In other words, they are weighted equally. Thus your grade so far would be the average of the three percentages:
With two lowest homework scores and two lowest quiz scores dropped: | ||
---|---|---|
(96.1 + 100 + 81) / 3 | = | 92.4% |
With no dropped scores: | ||
(78.0 + 94 + 81) / 3 | = | 84.3% |
You can see how much difference the drops make, especially at the beginning of the term. But beware: the more assignments we accumulate, the less difference the drops will make. So use your drops wisely!
Here's an example of what happens at the end of the term. Recall that the lowest of the 6 overall grades for Homework, Quiz, Midterm 1, Midterm 2, Midterm 3 and Final is dropped. Suppose your overall grades are as follows:
Homework | 87% | x 19/10 = | 165 points | |
Quizzes | 92% | x 19/10 = | 175 points | |
(dropped) | ||||
Midterm 2 | 86% | x 19/10 = | 163 points | |
Midterm 3 | 94% | x 19/10 = | 179 points | |
Final | 83% | x 19/10 = | 158 points | |
Effort/Attendance/Participation | 91% | x 5/10 = | 46 points | |
Total | 886 points out of 1000 = 88.6% |
You can see how the grade for Midterm 1, being the lowest of the first 6 grades, is dropped. Also note that if you are satisfied with your class grade going into the final, you can skip the final exam!
