What if my target percentage results in a fraction?

The calculator rounds up. If you need 35.5 correct, you must answer at least 36 correctly to meet or exceed the target.

Does this account for partial credit?

No, this assumes each question is either fully correct or incorrect. Adjust the target percentage down slightly for partial credit tests.

Skipped questions count as incorrect. The questions you can miss includes both wrong answers and skipped questions.

Calculate how many questions you need to answer correctly to achieve a target score or passing grade on a test.
