The Best Fit is the percentage students must reach in a level before it becomes automatically completed. This gives the students some leeway within the level. The Best Fit is set for the whole school and cannot be set for individual’s or groups.
When a level reaches this percentage, the level is changed to complete. You can turn off the best fit for individual levels if required. You can also mark levels complete earlier if required.
The best fit is set in My BSquared.
