Grading notes for a 24-question test
Twenty-four-question tests are common for unit tests split into equal sections, such as four sections of six or three of eight.
One wrong answer gives 95.83% (A) and two wrong answers give 91.67% (A-). To pass with 60%, a student needs 15 correct and can miss up to 9.
Because each question moves the score by 4.17%, only 10 of the 11 letter grades on the standard scale can actually be earned on this test: A+, A, A-, B+, B, C+, C, C-, D, F. No whole-number score lands on B-. Half-point scores can fill some of those gaps.
Because 24 divides evenly by 2, 3, 4, 6 and 8, it is an easy length to split into sections and report a score for each skill.
