How would a specific curve change my test score?

How we calculated this

An additive curve adds a flat number of points, capped at your maximum; a multiplicative curve multiplies the raw score, also capped. Using the example values above (80% raw, a 5-point additive curve, cap 100%), the curved score is 85%. If the raw score plus the curve would exceed the cap, the result is held at the cap instead.

Limitations

This models exactly the curve you specify; it does not predict whether your instructor will actually apply one, or which type. Treat this as "what if," not "what will happen."

Common mistakes

A common error is entering a multiplicative parameter as a percentage (110) instead of a multiplier (1.1), which produces a wildly incorrect curved score. Double-check that a multiplicative parameter is entered as a decimal multiplier, not a percentage.

Frequently asked

Can the curve lower my score?

A negative additive parameter or a multiplier below 1 would, though that is unusual for a curve in practice; the tool does not prevent it since it is your own scenario to test.

Why is there a cap?

Most curves are capped at 100% (or occasionally higher for extra credit); entering the cap that applies to you keeps the result realistic.

What is the difference between additive and multiplicative curves?

Additive adds the same flat number of points to every score; multiplicative scales every score by the same factor, which helps lower scores more in percentage-point terms than higher ones.

Can I test a curve before it is officially announced?

Yes, as a hypothetical; just remember the result reflects a scenario, not a confirmed grade change, until your instructor applies it.
