How to Brainstorm Ideas for IELTS Writing (Task 2 Method)

Published October 23, 2026 · Updated October 23, 2026 · 8 min read · by the Sakura5 team

To brainstorm ideas for IELTS Writing, spend the first three to five minutes of Task 2 turning the question into a short map: name the exact issue, write two or three reasons for each side you might take, attach one concrete example to every reason, then pick the side with the strongest examples and cut the rest. That’s it — question, reasons, examples, choose. It fits inside the 40 minutes recommended for Task 2 and stops you running out of things to say.

Most candidates skip planning because the clock feels too tight. The result is an essay that drifts, repeats the same point in different words, or answers a slightly different question from the one on the paper — all of which cost marks under Task Response and Coherence and Cohesion, two of the four criteria examiners use.

Below is why the usual approach goes wrong, a five-step method you can practise until it takes under five minutes, a full worked example on a real-style prompt, techniques for when your mind goes blank, and answers to the questions students ask most.

Why most IELTS essays run out of ideas

The problem is rarely a lack of opinions. It’s that candidates start writing the moment they understand the topic, and discover only halfway through body paragraph one that they have one good reason, not two. They then stretch that reason across both paragraphs, or invent a vague second one (“this is also important for society”) that carries no evidence.

A second trap is brainstorming the topic instead of the question. A prompt about public transport is not asking for everything you know about buses. It might be asking whether governments should spend more on transport than on roads, or what the causes of traffic congestion are and how to solve it. Ideas that fit the topic but not the task are the most common reason a well-written essay gets a low Task Response score.

The third trap is trying to brainstorm in English sentences. Full sentences are slow, and they make you judge each idea before you’ve finished having it. Keywords are faster, and you can turn them into sentences when you write. That’s why a branching map, not a list, is the natural format here — one reason can carry two examples, and an example can support either side.

How to brainstorm ideas for IELTS Writing in five minutes

1. Underline the task type and the exact issue

Before any ideas, identify what the question wants. Is it agree/disagree, discuss both views and give your opinion, advantages and disadvantages, causes and solutions, or a two-part direct question? Write the issue in the center of your map as a short question you could answer in one sentence: “Should university be free for everyone?” rather than just “education”. Every idea that follows must answer that question.

2. Branch out both sides, even if you already have an opinion

Draw two branches — for and against, causes and solutions, or whatever the task type demands. Give yourself about 90 seconds to put two or three reasons on each. Writing the side you disagree with is not wasted time: in a discussion essay you need it, and in an opinion essay it shows you which side actually has the better material.

3. Hang one concrete example on every reason

A reason without an example is a claim. Under each reason, add one specific, believable example: a type of person, a situation, a policy, a consequence. It doesn’t need to be a real statistic, and you shouldn’t invent one. “A nurse who graduates with large debts may leave for a better-paid job abroad” is concrete without pretending to be data.

4. Choose the side with the strongest examples

Look at your branches and pick the position you can support best, not the one you personally believe. IELTS does not mark your opinion; it marks how clearly you develop it. If one side has two reasons with sharp examples and the other has three vague ones, take the first.

5. Cut and order into paragraphs

Cross out anything that doesn’t serve your position. Number what’s left: one main idea per body paragraph, strongest point first or last depending on the structure you’ve practised. Now you have your essay plan, and you can write without stopping to think about what comes next.

If you prepare on your phone or laptop between practice tests, Mindmap AI fits this method closely: put the question in the center node, add branches for each side, and drag reasons around until the strongest ones sit together. When the map is done, outline view shows the same content as an ordered list — effectively your paragraph plan.

A worked example: a Task 2 opinion essay

Say Linh is preparing for the Academic test and wants Band 7. She practises with this prompt: “Some people think university education should be free for all students. To what extent do you agree or disagree?” She sets a timer for 40 minutes and allows herself five for planning.

Minute 0–1: the question. She notes the task type (agree/disagree, so she must take a clear position) and writes in the center: “Should all university be free?”

Minute 1–3: both sides. On the agree branch she writes: equal access for poor students; country benefits from more graduates; less student debt. On the disagree branch: heavy cost to taxpayers; not every student needs a degree; free places may lower quality if funding is spread thin.

Minute 3–4: examples. Under “equal access” she adds “talented student from a farming family who can’t afford fees”. Under “cost to taxpayers” she adds “money taken from primary schools and hospitals”. Under “not every student needs a degree” she adds “vocational training for electricians and chefs”. “Less student debt” gets no good example, so she marks it weak.

Minute 4–5: choose and order. She sees that a partly-agree position uses her best material on both sides: university should be free for students who can’t afford it, but not for everyone. Her plan becomes:

• Introduction — paraphrase the question, state partial agreement (about 40 words).
• Body 1 — free tuition for low-income students: equal access, the farming-family example (about 100 words).
• Body 2 — but universal free tuition is costly and unnecessary: taxpayer burden, vocational alternatives (about 100 words).
• Conclusion — restate the position in new words (about 30 words).

That totals roughly 270 words, safely above the 250-word minimum without padding. “Less student debt” and “lower quality” are cut because they had no examples. With the plan fixed, Linh writes for about 30 minutes and keeps five to check grammar and spelling. The essay has a clear position from the first paragraph to the last — exactly what Task Response rewards.

What to do when your mind goes blank

Some topics feel impossible — space exploration, art funding, the decline of local languages. When nothing comes, these prompts reliably produce reasons:

• Ask “who is affected?” Individuals, families, businesses, governments, the environment. Each one usually gives you a reason.
• Use the economic, social, and personal lenses. Money, how people live together, and individual health or happiness cover most IELTS questions.
• Think short term versus long term. Many policies cost now and pay later, or help now and harm later — that contrast is a ready-made pair of paragraphs.
• Bring it home. Imagine the issue in your own city or school. A local example is more vivid than a generic one, and examiners don’t need it to be famous.

For practice sessions, an AI assistant can help you see angles you missed — as long as you treat its output as a starting point to judge, not an answer to memorise. In Mindmap AI, a Pro feature lets you expand a node like “cost to taxpayers” into suggested sub-ideas, which is useful for building your topic bank at home. On test day, of course, it’s just you, a pen, and the five-step method. Our guide to brainstorming alone effectively has more prompts for getting unstuck without a partner.

What about Task 1?

Academic Task 1 needs less brainstorming and more selection: spend two or three minutes finding the overall trend and the two or three most significant features in the chart, then group the data around them. General Training Task 1 letters benefit from a quick map of the three bullet points in the prompt, with one detail under each so none gets forgotten. The official IELTS website has sample questions for both modules if you want material to practise on.

Turning your plan into paragraphs

A plan only helps if it shapes the writing. Each numbered branch becomes one body paragraph: open with a topic sentence that states the reason, explain it in one or two sentences, give the example, and link it back to your position. Don’t try to use every idea from the map — two well-developed body paragraphs usually beat three thin ones.

The same idea-first, sequence-second logic applies to longer academic writing too. If you’re also writing university essays, our walkthrough on organizing ideas before writing an essay scales this method up to 1,500 words and beyond.

FAQ

How long should I spend brainstorming in IELTS Writing Task 2?

Aim for three to five minutes of the recommended 40. That is enough to identify the task type, list reasons on both sides, attach examples and choose a position. Planning for longer than about seven minutes usually means rushing the conclusion or skipping your final check, which costs more marks than a slightly thinner plan.

Should I brainstorm both sides in an opinion essay?

Yes, briefly. Listing reasons for both sides takes about a minute and shows you which position has the stronger examples. You then argue that side clearly. IELTS examiners assess how well you develop and support a position, not whether they agree with it, so choose the side you can support best.

Can I use a mind map on the IELTS test?

You can sketch a quick keyword map on the question paper or scrap paper you’re given; only your answer is marked. On the computer-delivered test you’ll normally be given paper for notes too. Keep it to keywords and arrows — full sentences waste time you need for writing and checking.

How do I get better ideas for common IELTS topics?

Build a topic bank. After each practice essay, save your map and group maps by theme: education, environment, technology, work, health, government spending. Within a few weeks the same reasons and examples start recurring, so on test day you are adapting ideas you already know rather than inventing them under pressure.
