How a Student’s Overall Grade is Calculated

At times you may wish to confirm Easy Grade Pro’s calculations. Possibly, this will be at a student’s or parent’s request. The information here explains with examples how overall percents are calculated. We’ll use the same five assignments in all examples as shown.

Note that the Max. Score and Points Possible are taken from the assignments’ records; the % is found by dividing the score by the maximum score; and the Points Earned is found by multiplying the percent by the points possible. By the way, you can print a progress report for a student with all these values and more. (In the Report Options window for the progress report, be sure to turn on the Points Earned options for the Grade Summary and Assignment Charts.)

Example 1: A Simple Situation

If category weighting is not used, Easy Grade Pro tabulates the number of points the student has earned and divides this by the sum of the points possible on all graded assignments. If there are extra credit or negative points, then these are added to the points earned value before dividing. Here’s how:

1. Sum the points earned: 65 + 80 + 50 + 37.5 + 2 = 234.5

2. Sum the points possible: 100 + 100 + 50 + 50 = 300

3. Divide points earned by points possible: 234.5 / 300 = 78.17%

Example 2: Category Weighting

If category weighting is used, Easy Grade Pro goes through the calculations in Example 1 for each category. Then it weights the categories and combines them to produce the overall percent. In this example, the quiz category is weighted 60% and homework is weighted 40%.

1. Determine the quiz category percent: (65+80) / (100+100) = 72.5%

2. Determine the homework category percent: (50+37.5+2) / (50+50) = 89.5%

3. Weight the categories: ((72.5% x 60%) + (89.5% x 40%)) / (60%+40%) = 79.3%

Example 3: Combining Term Grades

What if one or more prior-term classes have been combined with the current class? What happens depends on whether the classes have been combined using points or weights.

If the terms have been combined using points, then it is a simple matter to sum all the points. For example, if the student above earned 234.5 out of 300 points this term and 222 out of 250 points last term, the student will have earned 456.5 out of 550 points or 83%.

If the terms have been combined using weights and each term is worth 50% of the grade and the student earned a 79.3% this term and an 88.8% last term, then the student will have earned ((79.3% x 50%) + (88.8% x 50% )) / (50% + 50%) or 84.05%.
