If you're wondering about how many students pass the IB, you've come to the right place. In this post we will breakdown the IB pass rate for both the May and November sessions.

May 2024 | 80.50% |

November 2020 | 75.77% |
May 2020 | 85.18% |

May 2019 | 77.81% |

At first glance, the statistics above might suggest that the November session is significantly more difficult, given its consistently lower pass rate – typically around 10 percentage points below that of the May session. However, this disparity can largely be attributed to the profile of students who sit the November exams. Many are from highly competitive, top-performing schools in the Southern Hemisphere, such as those in Singapore and Australia, where academic standards tend to be exceptionally high which in turn drives grade boundaries up.
