Which Grade Calculator Should You Use?
The best calculator depends on your grading situation. For example, if you know how many questions you answered correctly on a test, an Easy Grader or test grade calculator can help calculate the percentage. If your course uses homework, quizzes, exams and projects with different weights, a weighted grade calculator may be more appropriate.
- Use a test grade calculator for a single test or exam.
- Use a quiz grade calculator for quiz scores.
- Use a weighted grade calculator when categories have different percentages.
- Use a current grade calculator to review your grade from completed coursework.
- Use a final grade calculator when planning a desired course result.
- Use a percentage converter when you need to convert points or scores into percentages.
Common Grade Calculation Questions
What grade is 12 out of 15?
If all questions or points have equal value, 12 out of 15 is 80% because 12 divided by 15 and multiplied by 100 equals 80. The corresponding letter grade depends on the grading scale used by the course or instructor.
What grade is 43 out of 50?
43 out of 50 is 86%. The percentage can be calculated directly, while the letter grade depends on the grading scale that applies to the class.
How do I calculate a test percentage?
When questions have equal value, divide the number of correct answers by the total number of questions and multiply the result by 100. For a points-based assessment, divide points earned by points possible and multiply by 100.
How do I know what grade I need on my final exam?
A final grade calculation generally uses your current course grade, the percentage weight of the final exam and the desired overall grade. The result tells you the approximate exam score required under the assumptions entered into the calculator.
