| Understanding
the math behind the calculations of a student's overall grade can
help you use Easy Grade Pro more effectively. It can also help you
explain a student's grades when asked by an inquisitive parent or
student. Two examples will be used to explain the process and both
use the following five sample assignments: |
 |
| Let's
take a close look at this chart. The student is being graded on two
quizzes, two homework assignments and one extra credit homework. On
Quiz 1, the teacher set maximum score to 10 and points to 100. The
student's score is 6.5. Easy Grade Pro first calculates percent: (6.5/10)x100
= 65%. It then calculates points earned: 65% of 100 points possible
= 65. Take a moment to examine the numbers for the other assignments. |
| Example
1: When Category Weighting is Off |
| When
category weighting is off, Easy Grade Pro calculates an overall grade
by summing the points earned and dividing by the total points possible.
Here's how it does it: |
| 1 |
Sum
the points earned (last column): 65 + 80 + 50 + 37.5 + 2 = 234.5 |
| 2 |
Sum
the points possible (Points column): 100 + 100 + 50 + 50 = 300 |
| 3 |
Divide
points earned by points possible to get the overall percent: 234.5/300
= 78.17% |
| Example
2: When Category Weighting is On |
|
In this example, the Quiz category is weighted 30% and Homework is
weighted 50%. A third category, Final Exam, is weighted 20% but is
not yet being used. When category weighting is used, Easy Grade Pro
goes through the calculations in Example 1 for each category. Then
it combines the categories using the category weights to calculate
the overall percent. It works properly even though not all categories
are being used. |

Quiz |
Homework |
| 1. Sum the
points earned (last column): |
65 + 80 =
145 |
50 + 37.5 +
2 = 89.5 |
| 2. Sum the
points possible: |
100 + 100
= 200 |
50 + 50 = 100 |
| 3. Divide
to get the category percent: |
145/200 =
72.5% |
89.5/100 =
89.5% |
| 4.
Combine the categories percents using their weights to get the
overall percent: ((72.5% x 30%) + (89.5% x 50%)) / (30%+50%)
= 83.125% |
