I have updated the site with the official November 2024 grade boundaries. As a general rule of thumb, November grade boundaries are usually higher than May grade boundaries, so M25 candidates should use the M24 boundaries for the most reliable predictions. Additionally, Timezone 2 boundaries (Europe, Africa, Asia, Australia) are usually higher than Timezone 1 (North/South America).
If you are interested in contributing to IB Predict, please contact me via email or DMs on Discord for more details. I will continue updating the site for the foreseeable future. I am grateful for the level of support this tool has received and hope it can continue to serve future IB candidates long into the future.
Best of luck to all M25 candidates!

About sessions and timezones Optional reference
Choose the matching variant Use the boundary label supplied with your paper or results. Ask your coordinator when it is unclear.
Match the syllabus Compare sessions from the same course version whenever possible.
Treat 2020–2022 carefully Examination arrangements changed during the pandemic, so those sessions may not be directly comparable.
Compare like with like May and November sessions have different student groups. A past pattern does not determine a future boundary.
