Frequently Asked Questions
Are the Math AI grade boundaries the same every year?
No. IB grade boundaries can change from one exam session to another. The IB reviews the difficulty of each examination and adjusts boundaries to ensure grading standards remain consistent over time. As a result, the score needed for a particular grade in Math AI may be slightly higher or lower than in previous years.
How accurate are those Math AI grade boundaries?
The grade boundaries for Math AI shown on this page are taken directly from official documents published by the International Baccalaureate (IB). They reflect the official grade boundaries used for the selected examination session and can be considered fully accurate.
Are Math AI grade boundaries the same worldwide?
Not completely. The IB uses different exam time zones (typically TZ1 and TZ2) for some subjects, and students in different time zones may sit different paper variants. In these cases, grade boundaries are set separately for each time zone and paper combination, so they can differ slightly. However, within the same time zone and exam version, all students are graded using the same grade boundaries.
What score do I need to get a 7 in Math AI?
To achieve a grade 7 in Math AI, you need at least 66 out of 100 marks (66%) in this exam session, according to official IB grade boundaries.
What is considered a good score in IB Math AI?
Most universities consider a grade 6–7 in IB Math AI a strong result. A 7 is excellent, a 6 is very strong, and a 5 is a solid pass demonstrating good understanding.
How are Math AI grade boundaries calculated?
Grade boundaries are set after marking based on student performance in that exam session. The IB adjusts them each year so that grades reflect overall performance: if an exam is harder, boundaries are lowered, and if it is easier, boundaries are raised. This ensures a consistent distribution of grades across different sessions.
Can I use these Math AI grade boundaries to predict my final grade?
Yes. Grade boundaries can be a useful tool for estimating your final grade if you know your likely marks on each assessment component. However, predictions are never guaranteed because your final result depends on your actual Math AI exam and coursework scores, as well as the official grade boundaries for your exam session.
