What Is an Easy Grade Calculator?
An Easy Grade Calculator is an online grading tool that converts a raw score or points earned into an exact percentage and letter grade. It is commonly referred as Ez Grader. It applies a grading scale to show precise results for common formats such as x out of 10, 20, 25, 50, 60 and 100. Easy Grade Calculator is designed for academic grading, helping students and teachers quickly understand exam performance without errors or guesswork.
How the EZ Grader Works: Formula and Process
The grade calculator applies a single formula:

The ez grader converts the percentage into a letter grade based on a standard grading scale.
