What to Do When You're Stuck in an IB Math Exam

It happens to every student. You read a question, and nothing comes. The method isn't obvious, the numbers don't simplify the way you expect, and the clock is ticking.

What you do in that moment matters more than most students realise. Here is a clear strategy for exactly that situation — from someone who has marked thousands of papers and seen both sides of it.

First: don't panic, and don't stare

Panic narrows thinking. The moment you feel stuck, the worst thing you can do is freeze and stare at the question hoping it will become clearer.

It won't. Take a breath, put your pen down for ten seconds, and approach the question again with fresh eyes. This sounds trivial but it works — the brief mental reset is often enough to see something you missed the first time.

Re-read the question — slowly

Most of the time, being stuck is a reading problem, not a mathematics problem.

Read the question again, slowly, paying attention to every word. Look for:

• The command term — what is actually being asked?
• Any information you haven't used yet
• The connection to the previous part — is this a "hence" question?
• The mark allocation — how many steps does this require?

Students who feel stuck often find that careful re-reading reveals something they overlooked the first time — a given condition, a specific form required, or a link to an earlier result.

Write down what you know

Pick up your pen and write down everything you know about the problem — even if you don't know where it leads.

Write the relevant formula. Write the values you've been given. Write what you found in the previous part. Write what the question is asking for.

The act of writing organises your thinking and often reveals the next step. An examiner reading your working can award marks for correct setup even if you don't reach the final answer. A blank page cannot earn anything.

Try a different approach

If your first method isn't working, ask yourself whether there is another way to approach the problem.

In IB Math, most questions can be solved by more than one method. If an algebraic approach is getting complicated, consider whether a graphical or numerical approach would work. If you're trying to work forwards from the given information, consider whether working backwards from the answer might reveal the method.

Do something, even if it's partial

If you genuinely cannot see how to complete the question, do as much as you can and move on.

Set up the problem correctly. Write the method you would use if you knew the next step. Substitute the values you have. Attempt the parts you can see, even if you can't finish.

Partial working earns partial marks. A student who writes three correct lines before getting stuck earns more than a student who leaves the page blank.

Never leave a question entirely blank if there is anything at all you can write.

Move on and come back

If you've spent more than your marks-to-time allocation on a question and you're still stuck, mark it and move on.

Continuing to struggle with one question while the rest of the paper waits is one of the most costly time management errors in IB Math. A question you haven't attempted earns zero. A question you attempt imperfectly earns something.

Come back to the stuck question at the end if time allows — sometimes working through the rest of the paper gives you the insight you needed.

In Paper 3 specifically (HL)

Getting stuck on one part of a P3 investigation is almost inevitable. The question is designed to be challenging, and some parts will push you to the edge of what you know.

The rule is the same but even more important: never abandon the investigation. Write what you can for every part. The marks are distributed across many parts — losing one or two does not mean losing the question.

The mindset that helps most

The students I've seen handle being stuck best are the ones who treat it as a normal part of the exam — not a crisis. They expect to encounter at least one question they find difficult, and they have a plan for what to do when that happens.

That plan is what this article gives you. Practise it during your revision — deliberately put yourself in situations where you don't immediately know the answer — so that when it happens in the exam, you respond with method rather than panic.
