Frequently asked questions

What curving methods are available?

"Curve so the highest = target" shifts every score up by the same amount so the top score reaches your target maximum. "Add a flat number of points" simply adds a fixed number of points to every score.

Can curved scores exceed the target maximum?

No, curved scores are capped at the target maximum you set, so no student can score above it after curving.

How do I enter scores?

Separate scores with commas, spaces, or new lines - any combination works.
