• No categories (default) - Each gradebook item is assigned a simple point value. The course grade is determined by the student's total score divided by the total points possible.
• Categories only - Categories are used to group gradebook items, where items are assigned a simple point or percentage value. Similar to a gradebook with No categories, the course grade is determined by the student's total score divided by the total points possible. This structure provides the option to drop the lowest grade(s), keep the highest grade(s), or drop the highest grade(s) within a category.
• Categories and weighting - Items are grouped into categories, where each category is assigned a percentage of the course grade. The total score of all items in a category will comprise the category's percentage of the course grade. This structure provides the option to drop the lowest grade(s), keep the highest grade(s), or drop the highest grade(s) within a category.

## No categories

In a default gradebook with No categories, course grades are calculated for each student by dividing the sum of their scores received for all graded items by the total points possible for those items.

In the example pictured above, Student Five earned a total of 72 points out of 80 total points possible. His course grade is 72/80 = 0.90 (90%).

Note: Ungraded items are not included in a student's course grade. Leaving a grade entry blank reduces the total points possible by the point value of the ungraded item for that student.

In the example pictured above, most students were graded out of 80 total points. However, Student Three has not received a grade for Homework 2 (10 points possible). Thus, her course grade is 59/70 = 0.8429 (84.29%).
