IB Math AI SL 2026 Predictions: The Topics Most Likely to Appear

If you're revising for IB Math AI SL, the goal is not to revise every page with equal intensity. The goal is to focus hardest on the question types that keep returning. Recent past-paper patterns point to a small group of topics that deserve priority.

This is not about guessing the exact paper. It is about revising intelligently: spotting what IB repeatedly rewards, then training the method, structure, and calculator fluency that turn those topics into marks.

The 5 Math AI SL topics most likely to appear in 2026

1. Statistics and hypothesis testing

This is one of the most reliable areas in Math AI SL because it tests both technical skill and interpretation. IB likes questions where you must use your calculator correctly and then write a conclusion in context.

You should be ready for:

• Chi-squared tests
• Null and alternative hypotheses, H0 and H1
• Writing a valid conclusion in context
• Explaining whether the result is significant

2. Trigonometric modelling

IB Math AI SL consistently returns to real-world modelling, and trigonometric functions are a favourite because they test both graph understanding and interpretation.

Expect to work with:

• Amplitude and period
• Writing a trig model from context
• Solving trig equations
• Interpreting maxima, minima, and repeated patterns

The common mistake is treating the question like pure algebra. In Paper 2 especially, marks often depend on whether you explain what the value means in the real situation.

3. Financial mathematics

Financial maths is one of the clearest high-yield topics in the course. If you are aiming for efficient revision, this should be near the top of your list because it appears regularly and rewards strong calculator method.

You must know:

• Compound interest
• Annual depreciation
• Loan repayments
• Total interest paid over time

This topic is rarely about memorising complicated theory. It is about choosing the right calculator process, setting up values carefully, and checking whether the answer is realistic.

4. Probability: binomial and normal distribution

Probability remains common across both Paper 1 and Paper 2. IB likes switching between exact probability language and calculator-driven distribution questions, so you need both vocabulary and process.

Make sure you can handle:

• Binomial distribution questions
• Normal distribution probabilities
• “At least” and “exactly” wording
• Reading the question carefully before using technology

Many errors happen because students rush the phrasing. “At least,” “more than,” and “less than” do not mean the same thing, and IB uses those distinctions to separate accurate responses from careless ones.

5. Functions and optimisation

Functions are a core language of Math AI SL, and optimisation questions often appear as practical Paper 2 tasks. These questions test whether you can move from a model to a decision.

Be prepared to:

• Interpret graphs and function behaviour
• Find a maximum or minimum value
• Use derivatives where required
• Explain the real-world meaning of your result

A correct numerical answer is not always enough. If the question asks for the best dimensions, greatest profit, or lowest cost, say that explicitly in words.

Why students drop marks in Math AI SL

IB does not only assess whether you can get the final answer. It also rewards the structure of your working and the quality of your interpretation.

• Method: clear setup, correct calculator process, and visible working
• Accuracy: correct values, sensible rounding, and no careless notation slips
• Reasoning: explaining what the result means in the context of the question

This is one of the biggest reasons students stay around a 5 when they have enough knowledge for a 7. The content is often not the problem. The exam method is.

How to prepare efficiently

If your exam is getting close, do not spread your time evenly across the entire course. Build revision around repeated patterns and exam behaviour.

1. Prioritise the recurring high-yield topics above.
2. Practise full exam-style questions, not just isolated drills.
3. Review markschemes to see how conclusions are phrased.
4. Use your calculator until the process feels automatic.
5. Re-do missed questions and write one sentence explaining the mistake.

Final tip: the jump from a 5 to a 7

The difference between a 5 and a 7 in Math AI SL is often not raw knowledge. It is structure. Students who score highly usually do the same things well every time: they set up method clearly, use technology accurately, and interpret answers in context.

If you train the way examiners expect answers to be presented, your marks can rise quickly even before you finish revising every last topic.
