IB Results November 2025
General Trends
Overall performance was strongly in the middle achievement bands, with most candidates receiving grades between 4 and 6. Across all subjects combined, the overall mean subject grade was 4.6, confirming that results remained centred slightly above the passing threshold rather than being concentrated at the highest grade levels.
At a subject-group level, clear performance differences were observed between disciplines. The sciences recorded a mean grade of 4.4 across 21,477 students, while mathematics recorded a lower mean grade of 4.1 across 17,295 students. By comparison, language acquisition and language and literature subjects showed higher average scores, reinforcing the recurring pattern that mathematically intensive and analytical subjects produced lower average grades and a wider range of results.
A further trend observed in the data was the relatively small proportion of top grades in quantitative subjects. In both mathematics and the sciences, grades 6 and 7 accounted for a noticeably smaller share of results than grades 4 and 5, indicating that high-level mastery remained difficult to achieve.
Trends in Mathematics
In Mathematics: Analysis and Approaches (AA), results were more widely dispersed and overall performance was lower than in the applied pathway. At Higher Level, 3,384 candidates achieved a mean grade of 5.1, while at Standard Level, 7,871 candidates achieved a considerably lower mean grade of 3.9. The distribution in both levels was strongly centred on grades 4 and 5, with comparatively fewer students achieving grades 6 and 7.
In contrast, Mathematics: Applications and Interpretation (AI) showed a more favourable and stable profile. At Higher Level, 642 students achieved a mean grade of 4.1, and at Standard Level, 5,398 students achieved a mean grade of 3.6. Although both AI levels still showed clustering in the middle bands, the proportion of students achieving grades 5 and above was slightly higher than in the AA pathway.
Overall, the data confirmed that Mathematics AA remained the more academically demanding route, particularly at Standard Level, where the mean grade fell below 4.0. The applied and modelling-based structure of AI appeared to support more consistent performance for a broader range of candidates.
Trends in the Sciences
Across all science subjects combined, 21,477 students produced a mean grade of 4.4, placing the sciences below languages and close to mathematics in overall difficulty. Clear differences were observed between individual science disciplines and between Standard and Higher Level courses.
Biology showed the strongest overall outcomes within the sciences. At Higher Level, 3,354 students achieved a mean grade of 4.6, while at Standard Level, 5,117 students achieved a lower mean grade of 3.8. This gap indicated that the additional content and analytical requirements at Higher Level were associated with a noticeable reduction in overall performance.
Chemistry produced a more polarized profile. At Higher Level, 2,906 candidates achieved a comparatively high mean grade of 5.4, while at Standard Level, 3,098 candidates recorded a mean grade of only 4.1. This represented one of the largest HL–SL performance gaps in the sciences.
Physics continued to be one of the most demanding science subjects. At Higher Level, 2,353 students achieved a mean grade of 5.0, whereas 2,317 Standard Level candidates achieved a mean grade of 4.0. In both levels, a large proportion of students were concentrated in grades 4 and 5, with a noticeably smaller share reaching grades 6 and 7.
