How are grades calculated in Markboard?

**Assessments in Markboard are grouped by categories for marking**. Categories are averaged based on the weighting assigned on the settings page to get a students average. For example, if you have 2 categories, Quizzes and Homework, the average would be calculated as "studentAverage = (QuizAverage * QuizWeighting + HomeworkAverage * HomeworkWeighting) / (QuizWeighting + HomeworkWeighting)". If a category has no assessments it is not included in the average.

Now, let's take a look into **how each category average is calculated**. Within a category, each summative assessment is averaged -- *formative assessments do not contribute to the overall grade*. To customize how much a given summative assessment is worth within the category you can assign a custom weighting to it, by default this is set to 1. These weighting act like a multiplier and an assessment with 2x weighting will affect the average twice as much as an assessment with 1x weighting.

**Extra credit assessments** are a way that you can acknowledge when a student goes above and beyond what's expected. An extra credit assessment does not add itself to the number of assessments in a category. This means that if you have 3 regular assessments and 1 extra credit assessment, then the sum of the 4 assessments would be divided by 3 to get the category average. *Note: When you have extra credit assessments it is possible for your students to have a grade of > 100%.*

For each assessment, **the last attempt for each student is taken for their final grade**. If the last attempt is either omitted or ungraded then the assessment will not be counted towards their average.
