What is this tool?
A Grade Calculator is a free academic tool that computes your weighted course grade when different assignments, quizzes, midterms, and finals each carry a different percentage of the total mark. It solves one of the most common student dilemmas: "What score do I need on the final to pass – or to get an A?" Students, tutors, and teachers use it to track progress, simulate grade scenarios, and make data-driven study decisions before high-stakes exams.
How to use this tool?
1. List each graded component (homework, quiz, midterm, final) and enter the weight percentage it carries in the course.
2. Enter the grade or score you already received for each completed component.
3. Leave the final exam score blank – you'll calculate what you need.
4. Click "Calculate" to see your current weighted average based on completed work.
5. Enter your target final grade (e.g., 90% or an A) and the tool computes the exact final-exam score required.
6. Adjust weights or grades to run "what-if" scenarios and plan your study priorities.
