Predict your IB Maths grade

Enter your latest mock paper scores + how confident you feel across the syllabus. We'll compare that with the average of official IB grade boundaries from 2018 to 2025 and give you an honest predicted grade.

1. Your course

IB Maths course

2. Your most recent mock paper scores

Enter raw marks. Leave blank if you haven't sat it.

Paper 1 (out of 110)/110

Paper 2 (out of 110)/110

Paper 3 (HL only, out of 55)/55

IA (out of 20) — your teacher's estimate/20

3. Your confidence across the syllabus

This adjusts the prediction for topics you haven't been examined on yet.

Number, algebra & functions3

Geometry & trigonometry3

Statistics & probability3

Calculus3

Predictions use the historical average of official IB grade boundaries (2018–2025). The real boundaries for your exam session may differ. Treat this as a rough guide, not a promise. How IB Math grade boundaries work. IB Maths exam dates.

How the predictor works

It adds your Paper 1 and Paper 2 marks, and Paper 3 at HL. Your IA estimate out of 20 is then scaled so that full marks on the IA are worth a quarter of the exam papers' total, which makes the IA one fifth of the whole, as it is in all four IB Maths courses. Your four confidence ratings adjust the exam marks, because a mock only tests part of the syllabus: the exam total is multiplied by between 0.85 (every rating at 1) and 1.10 (every rating at 5). The result is compared with a threshold for each grade from 1 to 7, worked out from the average of official IB grade boundaries from 2018 to 2025 and rounded up to be cautious.

Getting a useful prediction

Use a full mock paper, sat in the real time and marked against its mark scheme.
A paper left blank counts as zero, so the prediction only means something once you have a mark for each paper.
Ask your teacher for an IA estimate out of 20 rather than guessing.
Run it again after each mock. The marks needed for the next grade is the number to aim at.

Boundaries change every session, so treat the grade as a guide. To find the marks: see where students lose marks, and practise by topic for AA SL, AI SL, AA HL or AI HL.
