15-Question Test Grading FAQs
How much is each question worth on a 15-question test?
On a 15-question test, each question is worth exactly 6.67% of the total score (calculated as 100 ÷ 15). Because this size produces fractional percentages, standard academic half-up rounding converts repeating fractions into whole number percentages.
How many questions can you miss to get an A on a 15-question test?
Under the standard 10-point scale (90% minimum for an A), you can miss at most 1 question. Scoring 14/15 yields an exact score of 93% (A). Missing 2 drops the score into the B range.
How does rounding work on a 15-question assessment?
With standard academic half-up rounding, fractional percentages ending in .5 or greater round up to the next integer, while fractions below .5 round down. For example, on this 15-question test, missing 1 question gives 93.3%, which rounds to 93%.
