Frequently asked questions
How do I calculate my test grade percentage? ›
Divide the number of correct answers by the total number of questions, then multiply by 100. For example, 36 correct out of 40 total = (36 ÷ 40) × 100 = 90%. This calculator does that math instantly.
What is a passing grade? ›
Most schools consider 60% (D−) or 70% (C−) as the minimum passing grade, but this varies by institution, course, and program. Graduate programs often require a B (80%) minimum to pass. Always check your syllabus for the specific passing threshold in your course.
Does my teacher use a different grading scale? ›
Some schools use a 10-point scale (90–100 = A) while others use a 7-point scale (93–100 = A). The standard scale shown above is the most common in US higher education, but your teacher's syllabus will have the exact scale used in your course. You can verify by comparing a known grade.
How does one test affect my overall grade? ›
It depends on how your teacher weights different assignments. A test worth 25% of your grade has a proportional impact on your final score. Use our Grade Calculator to see exactly how this score affects your overall course grade, or our Final Grade Calculator to find out what you need on remaining assignments to hit your target.
