Frequently asked questions
- How do I calculate my grade average?
- Enter each grade and, if some count more than others, a weight next to it. The calculator multiplies every grade by its weight, adds them up, and divides by the total weight. Leave the weight blank and each grade counts equally.
- What grade do I need to pass my exam?
- Use the "What do I need?" tab. Enter your current average, how much the final exam is worth as a percentage, and the overall grade you are aiming for. It tells you the minimum grade you need on that final.
- How do I convert a grade between countries?
- The "Convert" tab maps a grade from one system to an approximate equivalent in the Dutch, Belgian, German, UK, US and IB systems. These are guidance only, since there is no official conversion and each university publishes its own table.
- Is this grade calculator free?
- Yes, it is free to use with no account and nothing to install. If you want a hand raising your grades, you can book a 1-on-1 tutor.
