For your grading system, you can choose Total points or Weighted by category grading. In both, grades are calculated for you, and you can let students check their overall grade for the class. If you don’t want to use a grading system, you can choose No overall grade. Grades won’t be calculated and students can’t check their overall grade.

You can also organize classwork with grade categories, such as Essays, Homework, and Tests. For example, if your class has 4 essay assignments, you can organize them in an Essays category.

Grades are calculated for the duration of the class. If you want to begin grading again for a new term or semester, you have to create a new class. For details, go to Copy a class.

To have grades calculated for you and an option to let students check their overall grade, use Total points or Weighted by category grading.

An overall grade is calculated for you by dividing the total points a student earns by the total points possible in the class. You can create grade categories and set point values for classwork in each category. For example:
 Essay category Test category Student points/Points possible Overall grade Essay 1: 90/100 Test 1: 95/100 185/200 92.5%
The table shows that a student scored 90 points out of 100 on an essay, and 95 points out of 100 on a test. The student earned a total of 185 points out of 200 possible in the class. Divided, this gives an overall grade of 92.5%.
Tip: Assignments with a grade set to "Excused" are removed from a student's grade calculation. For example, if a student has 5 assignments with a score of 100%, but doesn’t turn in one assignment that’s set to "Excused," the student will still keep an average grade of 100%.

You assign weights (percentages) to grade categories, and an overall grade is calculated for you. This system calculates as follows:
1. Finds a student's average for a category.
2. Multiplies each category’s average by its weight (as a decimal), giving category scores.
3. Adds the category scores for an overall grade out of 100%.
 Essay category:  50% of grade Test category: 50% of grade Overall grade out of 100% Essay 1: 70/100 Test 1: 90/100 Essay 2: 80/100 Test 2: 100/100 (70 + 80) ÷ 2 = 75 avg.  75 x .5 = 37.5 (90 + 100) ÷ 2 = 95 avg. 95 x .5 = 47.5 Category score = 37.5% Category score = 47.5% Overall grade: 37.5 + 47.5 = 85%

The table shows weighted by category grading. In the Essay category, the student averaged 75. Multiplied by the category weight, .5, this gives 37.5% for Essays. In the Test category, the student averaged 95. Multiplied by the category weight, .5, this gives 47.5% for Tests. Adding the category scores (37.5 + 47.5) gives the student an overall grade of 85%.

Tip: Assignments with a grade set to "Excused" are removed from a student's grade calculation. For example, if a student has 5 assignments with a score of 100%, but doesn’t turn in one assignment that’s set to "Excused," the student will still keep an average grade of 100%.
