Grading notes for a 15-question test
Fifteen questions is one of the most common quiz lengths in middle and high school, especially for chapter quizzes and reading checks.
One wrong answer gives 93.33% (A) and two wrong answers give 86.67% (B). To pass with 60%, a student needs 9 correct and can miss up to 6.
Because each question moves the score by 6.67%, only 7 of the 11 letter grades on the standard scale can actually be earned on this test: A+, A, B, B-, C, D, F. No whole-number score lands on A-, B+, C+, C-. Half-point scores can fill some of those gaps.
12/15 is exactly 80%, the lowest B-, so three misses is still a B-. Because 15 doesn't divide evenly into 100, many scores land on repeating decimals (13/15 = 86.67%), so check whether your gradebook rounds before you compare students.

An A (93% or higher) needs 14 correct out of 15, so you can miss 1. A B (83% or higher) needs 13 correct, so you can miss 2. On a 10-point scale, where an A starts at 90%, the numbers are a little more forgiving.
