Frequently asked questions
What is an easy grader? ›
An easy grader (also called a grading scale generator or grading chart) is a tool teachers use to quickly find the minimum number of correct answers required for each letter grade on a specific test. Instead of calculating manually for every student, you enter the total questions and the chart does all the math at once.
How many questions can a student miss and still pass? ›
It depends on the total number of questions and your passing threshold. On a 40-question test with a 70% passing grade, a student can miss up to 12 questions. On a 25-question test, they can miss up to 7. The generated chart above shows the exact numbers for your specific test.
What is a standard grading scale vs. a plus/minus scale? ›
The standard scale uses simple letter grades: A (90–100%), B (80–89%), C (70–79%), D (60–69%), F (below 60%). The plus/minus scale adds finer gradations — A+, A, A−, B+, B, B−, etc. — which gives students more nuanced feedback and affects GPA differently at colleges that use plus/minus weighting.
Can I use this for quizzes and homework too? ›
Absolutely. This tool works for any scored assessment — tests, quizzes, homework assignments, projects with rubrics, or any other scored work where you want to convert a raw score to a letter grade. Just enter the total number of points or questions.
