What is an Easy Grader?
An Easy Grader (also known as an EZ Grader or grade calculator for teachers) is a quick reference tool designed to streamline the grading process. Instead of manually calculating percentages for each test, teachers simply enter the total number of questions and the number of wrong answers. The tool instantly converts these inputs into a percentage score and the corresponding letter grade based on a standard or customized grading scale. This makes batch grading faster and reduces arithmetic errors, allowing educators to focus more on teaching and less on paperwork.
