Grading notes for a 13-question test
Thirteen-question tests usually happen when a teacher drops or adds one item from a 12- or 14-question set.
One wrong answer gives 92.31% (A-) and two wrong answers give 84.62% (B). To pass with 60%, a student needs 8 correct and can miss up to 5.
Because each question moves the score by 7.69%, only 6 of the 11 letter grades on the standard scale can actually be earned on this test: A+, A-, B, C, D, F. No whole-number score lands on A, B+, B-, C+, C-. Half-point scores can fill some of those gaps.
Odd totals like 13 produce long decimals, so pick one rounding rule (for example, round to the nearest whole percent) and apply it to every paper in the set.
