Frequently asked questions
Is this the same as the Exam Score calculator?
It uses the same underlying maths but is designed for any assessment type, not just exams — assignments, quizzes or overall subject totals.
Can total marks be zero?
No, the calculator needs a positive total to work out a percentage and will show an error otherwise.
Are the letter grade cut-offs standard nationally?
No — they're a common convention only. Always check your school or university's official grading scale.
