Course grade calculations depend on your Gradebook's organization and grade entry setting, points (described here) or percentages:
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%).
With Categories only, course grades are calculated the same as in a gradebook with No categories (described above). However, if all items in a category have the same total point value, you can automatically drop the lowest or highest grades or keep the highest grades within that category. Dropped grades are omitted from the course grade calculation, and the total points possible in the category are reduced by the point value(s) of the omitted item(s).
By using the Keep Highest option instead of Drop Lowest to drop the lowest grade(s), no grades will be dropped in the category until the number of items kept is exceeded.
See below example calculations when grades in a category are dropped or kept.
Note: You must assign each item to a category for the item to be included in students' course grades.
Grades can only be entered in gradebook items; you cannot enter grades into a category with no items.
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.
Pictured above is a gradebook with two categories: Assignments and Quizzes. The Assignments category drops the lowest grade, and includes two assignments, each worth 10 points. The Quizzes category includes Quiz 1 (10 points) and Quiz 2 (20 points). There are 40 points possible because only one assignment and the two quiz grades are included in the course grade calculation.
In our example, Student Five received the following grades:
Assignments:
Quizzes:
Since the Assignment 2 grade is dropped for Student Five, his course grade is 95%:
Pictured above is a gradebook with two categories: Assignments and Quizzes. The Assignments category keeps the two highest grades, and includes three assignments, each worth 10 points. The Quizzes category includes Quiz 1 (10 points) and Quiz 2 (20 points). There are 50 points possible because only two assignments and the two quiz grades are included in the course grade calculation.
In our example below, we will use the Keep Highest option versus Drop Lowest to show how it affects Student Five's course grade.
Before the third assignment grade is entered, Student Five received the following grades:
Assignments:
Quizzes:
No grades are dropped yet because we have used the Keep Highest option, so Student Five's grade is 92%:
In comparison, if Drop Lowest were used instead, Student Five's grade would have been calculated as only 36 points earned out of 40 points (95%), as shown in the example above where the lowest grade of two assignment is dropped.
Now we enter the third assignment grade. The highest two assignment grades are kept, so the lowest assignment grade (Assignment 3) is dropped:
Assignments:
Quizzes:
Student Five's grade is still 92%:
Keeping the highest grades instead of dropping the lowest grades ensures that Student Five's grade is calculated out of the same number of total points (50 points) both before and after entering the third assignment grade.
If the Drop Lowest option had been used instead, the calculated course grade for Student Five would have been calculated out of 40 points before entering the third assignment grade. The course grade would have decreased significantly after the third assignment grade was entered, going from an A (95%) down to an A- (92%).
Use Categories & weighting to group gradebook items into categories, and weight each category as a percentage of the total course grade. The sum total of all category percentages must equal 100% (or more, if there is an Extra Credit category).
For example, if Exams are worth 20% of the course grade, the Exams category (20%) could include a Midterm Exam (50 points) and Final Exam (100 points).
Each student's course grade is the sum of the categories' weighted averages. See below for additional information about dropping and keeping grades, and example calculations.
Note: You must assign each item to a category for the item to be included in students' course grades.
Grades can only be entered in gradebook items; you cannot enter grades into a category with no items.
Ungraded items are not included in a student's course grade. If any grade entry is left blank, the total points possible within the category are reduced by the point value(s) of the ungraded item(s) for that student.
If all items in a category have the same total point value, you can automatically drop the lowest or highest grades or keep the highest grades within that category. Dropped grades are omitted from the course grade calculation, and the total points possible in the category are reduced by the point value(s) of the omitted item(s).
By using the Keep Highest option instead of Drop Lowest to drop the lowest grade(s), no grades will be dropped in the category until the number of items kept is exceeded.
Below is an example of how a Gradebook with three weighted categories, Exams (20%), Assignments (40%), and Quizzes (40%), would calculate a student's grade.
Tip: The category average is shown in a column to the right of the gradebook items in that category.
If Student One received a category average of 75% for Assignments and 85% for Quizzes, his course grade is 82%, calculated as follows:
