**Unweighted/Total Points Grading**

If assignment categories are **not **weighted, Engrade will calculate students' class percentage based on a total points system. This is calculated individually for each student as:

**Student class percentage = total points earned / total points possible**

As an example, imagine the following grades for a student in your class:

** Homework ** | 160/200** Quizzes ** | 70/100** Final Exam **| 0/0

To calculate the student's overall grade, perform the following calculation:

- Add each category's points earned together, and add each category's points possible together: (
**160**) + (**70**) + (**0**) / (**200**) + (**100**) + (**0**) - Divide the sum of the total points earned by the sum of total points possible: (
**230**) / (**300**) - Find the student's overall class average:
**76.67%**

Any points a student is given for an extra credit assignment are added directly to the student's total points earned, while his/her total points possible will stay the same. If you assign a student a score of E (excused) for an assignment or leave his/her score blank, then that assignment will be ignored and not affect either the student's total points earned or total points possible. A score of M (missing) on an assignment will be graded as if the student had earned 0 points possible on the assignment.

**Weighted Assignment Categories**

If assignment categories **are** weighted, Engrade will calculate each students' class percentage as follows:

**Student class percentage = ****(category A weight * category A points earned / category A points possible ) + ****(category B weight * category B points earned / category B points possible ) + ****(category C weight * category C points earned / category C points possible ) + ****... and so forth**

Each category's grade is calculated exactly the same as the total points system listed above, the only difference is that Engrade then multiplies each category percent by the weight assigned to it. Then, the results from each category are added together to create a final percentage. If there are weighted assignment categories that do not yet have graded assignments, Engrade will automatically compensate by ignoring unused categories and **proportionately** re-weigh existing categories to make a sum of 100%. For example, imagine the following grades for a student in your class:

** Homework | Weight: 25%** | Points: 160/200 | Student Average: 80%** Quizzes | Weight: 25%** | Points: 70/100 | Student Average: 70%** Final Exam | Weight: 50% **| Points: 0/0 | Student Average: None** **

Since no graded assignments have been added for the Final Exam category (set to be weighted at 50%), this 50% weight is **proportionately** dispersed across the other weighted categories. To ensure you are obtaining a **proportional** average, perform the following calculation:

- Add the total weights of the graded categories:
**25%**+**25%**=**50%** - Divide each graded category by the sum of the graded categories:
**25%**/**50%**=**50%**and**25%**/**50%**=**50%** - Determine the adjusted category weights:
**50%****50%**

Now, the **Homework category is weighted at 50%** (the original **25%** weight + **25%** from the Final Exam category) and the **Quizzes category is weighted at 50%** (the original **25%** weight + **25%** from the Final Exam category).

** Homework | Adjusted Weight: 50%** | Student Average: 80%

**Quizzes |**| Student Average: 70%

**Adjusted**Weight: 50%**Final Exam |**| Student Average: None

**Adjusted**Weight: 0%Therefore, the student’s current grade is figured as:

- Multiply each category's overall percentage by its adjusted category weight: (
**80%*****50%**) + (**70%*****50%**) - Add the weighted percentage from each category together: (
**40%**) + (**35%**) - Find the student's overall weighted class average:
**75%**

When a graded assignment is added into the **Final Exam** category, the weights of the **Homework** and **Quizzes** categories will re-assume their preset weights (25% each) and graded assignments in the **Final Exam** category will be weighted at 50%.
