IB subjects are graded on a scale from 7 to 1. A total of 3 additional points may be awarded to students for Theory of Knowledge (TOK) essays and extended essay (EE) components, contributing to the overall grade.
Students must successfully obtain a minimum of 24 points to pass. The maximum points that can be achieved are 45 points, with 42 points generated across their six 6 subjects and 3 bonus points derived from Theory of Knowledge and the Extended Essay.
UCAS have developed a tariff system that gives greater currency to the IB scores over A-Levels. For example, an IB score of 38/45 equates to five A grades at A-Level standard.
