GRADE BOUNDARY CALCULATOR

This calculator converts marks scored into a percentage, then compares that percentage with editable grade boundaries.

Use it for mock exams, practice papers, homework quizzes, class tests and quick grade checks.

Enter marks scored and total marks. Choose a boundary set, then edit the boundary percentages to match your paper.

Press SOLVE to show percentage, threshold and estimated grade.

The percentage is compared with the boundary list from highest to lowest. The first threshold reached becomes the estimated grade.

With GCSE 9-1 defaults, 60% reaches the grade 7 threshold. Change boundaries for your exact exam board and paper.

The set menu loads starter boundaries for common grading styles.

The values are editable because official grade boundaries vary by exam board, year, qualification and paper.

This tool gives a calculation estimate only. It does not replace official exam-board grade boundaries or final results.

Always use official boundaries when accuracy matters.

Students use it to estimate grades after mock papers. Teachers and tutors use it for fast mark checks, target setting and classroom feedback.

Parents can use it to understand how marks, percentages and boundaries connect.

After estimating a grade, you may want to calculate mark percentage, target grade, weighted average, pass threshold or overall grade.
