Q: How are **Subtotal** grades calculated in the Gradebook?

A: Gradebook subtotals are calculated by taking the number of points a Student earned divided by the number of points available to be earned.

If the Gradebook has **Weighted Categories**, after determining the subtotal for the **Category** by taking points earned out of points available, the **Category weights** are used to come up with the **Subtotal**.

**Simple Gradebook (no Categories)**

In a Simple setup--a Gradebook that does not use **Categories**--all entries are averaged to find the final grade.

For example:

A Gradebook has four entries with the following values for one Student: 80/100, 70/100, 40/50, 6/10. The Student's final grade will be calculated by adding points earned (80+70+40+6), then dividing by points available (100+100+50+10). So, in this case, the Student's grade is 196/260, or 75%.

**Gradebook with Categories (not weighted)**

In a Gradebook with **Categories **that are **not weighted**, the final grade calculation is exactly the same as in the Simple setup. All entries are averaged to get the Final Grade.

**Gradebook with Weighted Categories**

In a Gradebook with **Weighted Categories**, all entries in each category are averaged (by taking, as above, the points earned out of the points available), then all categories are averaged together according to their weight.

Category 1 (25%): ((90/100)*.25)=.225

Category 2 (75%): ((80/100)*.75)=.60

Category 1 (.225) + Category 2 (.60) = .825 = **82.5%**
