The calculator combines your scores from each assessment component using official IB weightings for every subject. It then uses historical IB grade boundaries from a past session to estimate your overall diploma score and predicted grades.

This calculator uses official IB component weightings and historical grade boundaries to estimate your results. While it can provide a strong indication of your likely grades, your actual results may differ if the official grade boundaries for your exam session change.

Yes, but only as an estimate. The calculator predicts grades based on the marks you enter and past grade boundaries. Your actual grades will depend on your final component scores and the official grade boundaries for your exam session.

Enter your best estimate for each assessment component. If you already have marks for coursework or Internal Assessments, use those values directly. For exams you have not taken yet, use your predicted or expected scores.

Teachers often consider factors beyond raw marks, such as class performance, coursework quality, and expected improvement before exams. This calculator uses only the marks you enter and historical grade boundary data.
