IB Maths AI SL grade boundaries by session

Mark ranges are inclusive — “42–54” means 42, 43 … 54 all earn that grade. Overall is the composite total out of 100 scaled marks. The percentage beneath each range is of that component's own maximum for that session, because paper totals shift slightly from one session to the next.

Is the Grade 7 boundary rising?

Averaged across the record, the Grade 7 threshold in the later sessions sits about 2.7 percentage points higher than in the earlier ones. In practice that means recent cohorts have needed a slightly larger share of the marks for a 7 than students sitting the earlier papers did.

How to read these boundaries

Grade boundaries are not fixed targets. The IB resets them after every session so that each grade represents the same standard of work, whether that session's paper ran hard or easy. That is why the mark needed for a 7 in IB Maths AI SL can move by several points from one session to the next while the syllabus stays identical.

For revision, use them as a calibration tool: sit a past paper under timed conditions, mark it against the official markscheme, then check what that total would have earned in the session that paper is from — not the most recent one. Comparing your marks component by component, rather than only the overall total, is what tells you where the marks are actually going.

The 6-to-7 gap is small

Across these sessions the distance between a 6 and a 7 has averaged just 14.1 marks out of 100 (narrowest 12, widest 17). On a paper marked out of 100 scaled marks, that is a handful of well-argued sentences.

Use the right session

The Grade 7 boundary here has swung 17 percentage points between May 2025 TZ2 (66%) and November 2025 TZ3 (83%). Marking a past paper against the wrong session's boundaries can mislead you by a whole grade.

Components move independently

The overall boundary is a composite. Individual papers are graded on their own scales and can be far more or less forgiving than the overall figure suggests, which is why every component is listed separately in the tables above.

Frequently asked questions

What percentage do you need for a 7 in IB Maths AI SL?

Across the 14 sessions on record, the overall Grade 7 boundary for IB Maths AI SL has ranged from 66% (May 2025 TZ2) to 83% (November 2025 TZ3) of the 100 available scaled marks. In the most recent session on this page, May 2026 TZ3, it was 76%. There is no fixed percentage: the IB resets the boundary after every session so that a 7 represents the same standard of work regardless of how hard that particular paper turned out to be.

How many marks separate a 6 from a 7 in IB Maths AI SL?

On the overall 100-mark scale, the gap between the Grade 6 and Grade 7 boundaries has averaged 14.1 marks, ranging from 12 to 17 marks. In May 2026 TZ3 a 7 started at 76 and a 6 at 63 — a 13-mark gap. That is a much smaller distance than most students assume, and it is usually closed with exam technique rather than extra content.

Do IB grade boundaries change every year?

Yes. They are set after each examination session by the IB's grade award process, once senior examiners have seen how candidates actually performed on that specific paper. For IB Maths AI SL the overall Grade 7 threshold has moved by 17 percentage points between its lowest and highest session on record. This is why you should always compare a past paper score against the boundaries from the session that paper is from, not the most recent session.

Why are there different timezones (TZ1, TZ2, TZ3) for IB Maths AI SL?

Candidates in different parts of the world sit different versions of the same examination so that papers cannot be leaked across time zones. Each version is graded separately with its own boundaries, which is why you will see TZ1, TZ2 and TZ3 listed with slightly different thresholds for the same month. Always use the boundaries for the timezone your paper was actually sat in.
