IB Score Calculator
Total an International Baccalaureate diploma score including core points.
About IB Score Calculator
Six subjects contribute up to 42 points and the core adds up to three more. The diploma also requires minimum grades per subject and a higher level total, so the aggregate alone is not sufficient. A strong total can still fail the diploma if a single subject falls too low, which is why the conditions matter as much as the sum.
