Is 11 Out of 15 a Good Grade?
11 out of 15 is an average result. You answered about three out of four questions correctly, which is a safe pass at most schools, though it sits in the middle of the grade range. On the plus-minus scale, it is a plain C, about 3 percentage points above the 70% line that some programs use as a minimum.
A C often reflects a decent grasp of the main ideas with room to tighten the details. With 4 misses, you are a single question away from a B, so small habits like re-reading each question and checking calculations can change the grade.

When 11/15 May Not Match Your Final Grade
The calculator gives the grade for this one score. These six things can change how it counts toward your final grade:
Weighted Categories
A quiz counts only as much as your teacher weights it. At a 10% weight, 73.33% adds about 7.33 of the 10 available points.
Extra Credit
11/15 plus 1 bonus point becomes 12/15 (80%). Some teachers allow totals above 100%.
Dropped Scores
Some courses drop your lowest quiz or test. If yours does, a weaker score may not count at all.
Curved Tests
If the test is curved, apply the curve first and then convert the new score to a percentage.
Rounding Rules
Rounding 73.33% to 73% keeps you in the C range on both scales, so rounding does not change this grade.
Pass/Fail Courses
In pass/fail courses, only your school’s cutoff matters, usually 60% or 70%, and a letter may not be shown.
If your recorded score ever looks wrong, remember that 11 ÷ 15 is always 73.33%, so ask your teacher to check it.
Real Examples With 11 Out of 15
A pass-or-fail cutoff. Whether the cutoff is 60% or 70%, 73.33% clears it. The margin is small, though: 10/15 (66.67%) would fail a 70% cutoff.
Moving up to a B. One more correct answer gives you 12/15, which is 80%, a B on the standard scale.
Averaging three quizzes. Scores of 11/15, 13/15, and 12/15 add up to 36/45, which is 80%. A weaker quiz can be balanced by a stronger one.
How to Improve Your Grade
Moving from a C to a B takes just 1 more correct answer. Check whether your 4 wrong answers were careless mistakes, such as misreading a question or making a sign error, or real knowledge gaps. Careless errors are the fastest to fix, because the knowledge is already there. Reserve the last few minutes of a test for re-checking answers.
- Mark each of the 4 missed questions as a careless error or a knowledge gap.
- Fix the careless errors first, because you already know that material.
- Set a target of 12/15 on the next test, which is a B on the standard scale.
