Frequently Asked Questions

What curve method does this use?

This uses a flat-shift curve: the difference between the target average and actual class average is added to every score, scaled by curve strength.

What does curve strength mean?

100% applies the full calculated shift; lower percentages apply a partial curve, useful for comparing softer curving policies.

Can a curve lower my grade?

Yes — if the class average already exceeds the target average, the shift will be negative and could reduce scores.
