Once you have added assignments to your Assignment Group, you can create rules for the entire Assignment Group. Assignment Group rules determine how Curve handles any exceptions you want to create for grade calculations. Assignment groups can be weighted or unweighted.
When using the lowest or highest score rule, Curve considers how the rule most negatively or positively affects the student's overall score. In some cases, point values may be considered more important than an overall percentage score. For example, an instructor may set a rule to drop the lowest score in the Assignment Group, where a student with a failing grade earns a 100% on a 10-point assignment and 75% on an 100-point assignment. Even though in the first assignment the student earned 100%, the 10-point value is not as significant (as compared to the 100-point assignment) and will be dropped because it has a much lower impact on the student's overall score.
Note: Curve drops the score with the lowest percentage regardless of its effect on the final grade if all of the following conditions are met:
- Your assignment groups are not Weighted.
- Multiple assignment groups have a grading rule to drop the lowest assignment.
- An assignment group contains assignments with varying point values.
