EZ Grader

The tool provides a web‑based calculator that converts the total number of questions and the number of incorrect answers into a final percentage and optional letter grade. Users enter the question count, then mark wrong answers manually, via keyboard shortcuts, or with a “+1” button; the result updates instantly. A reset function clears the fields for the next student, and a quick‑chart view shows grading thresholds.

It is aimed at teachers who need to grade quizzes, tests, or assignments efficiently, especially when handling multiple papers. By automating the conversion from raw scores to percentages, the calculator reduces the time spent on manual arithmetic and eliminates common calculation errors. The interface presents results in a clear, easy‑to‑read format, making it suitable for classrooms of any size.

The application is lightweight, accessible through a browser, and requires no installation. It supports basic keyboard shortcuts for rapid data entry and offers a reset button to streamline grading of successive assessments. The design focuses on simplicity and speed for everyday educational grading tasks.
