🔶 Part 1 — Tutorial

Step 1 — Analyse the task & choose a position (Agree/Disagree)

Read the prompt slowly and highlight the command phrase “To what extent do you agree or disagree?”; this tells you to give a clear stance with a measured degree. Identify the topic scope (“university education”) and the policy claim (“should be free for everyone, regardless of income”). Clarify key terms: “free” usually means tuition-free at point of use; it does not mean zero cost to society because someone still funds it via taxes. “Regardless of income” excludes means-testing, so consider equity and efficiency angles. Decide your position quickly: fully agree, largely agree with caveats, partly agree (e.g., free for first degree only), or disagree in favour of targeted support. Generate two to three defensible reasons that you can explain with simple mechanisms and micro-examples. Check that your reasons are distinct (e.g., access & social mobility vs economic burden & opportunity cost) and not duplicates. Avoid vague morality claims without mechanisms; show how the policy leads to benefits or problems. Consider typical counterpoints such as tax burden, overcrowding, degree inflation, and alternative funding models (e.g., income-contingent loans). Decide whether to include a short acknowledgement of the other side to sound balanced. Keep the question visible while planning so every sentence later points back to the claim. Finally, form a one-sentence thesis that states your extent clearly and previews your two main reasons.

Example Box — Decoding the Prompt

Prompt: “University education should be free for everyone, regardless of income. To what extent do you agree or disagree?
Focus: Policy (tuition-free), Universality (no means-testing), Stance (extent).
Possible stances: (A) Largely agree: boosts access and growth, with quality safeguards; (B) Partly agree: free for first degree/low-income only; (C) Disagree: targeted aid and income-contingent fees are fairer/sustainable.

Step 2 — Plan a clear structure & argument flow

Use a compact four-paragraph model for control under time pressure. The introduction should paraphrase the claim in one sentence and give a direct thesis in the next, naming two reasons. In Body 1, lead with your strongest reason (e.g., widening participation and social mobility) and explain the mechanism step by step. Add a short, credible micro-example (a country, a cohort, or a plausible scenario) instead of statistics you cannot defend. In Body 2, give a second, distinct reason (e.g., long-term economic benefits) or present a balanced view by acknowledging a key concern (e.g., fiscal burden) before showing why your position still holds. Keep one central idea per paragraph and avoid laundry lists. Use topic sentences that answer the question directly and signal the paragraph focus. Link sentences logically with cause/result (“therefore,” “as a result”) and reference words (“this policy,” “such costs”). The conclusion restates your extent of agreement and synthesises your two reasons without new information. Allocate time: ~8–10 minutes plan, ~28–30 minutes write, ~2 minutes check. Aim for ~270–310 words for full development while remaining concise and precise.

Example Box — Skeleton Plan

Intro: Paraphrase + thesis: largely agree because of access/mobility and long-term growth, while noting funding safeguards.
Body 1: Access → more graduates from low-income backgrounds → higher lifetime earnings → social mobility (micro-example).
Body 2: Human-capital gains → innovation/productivity; acknowledge tax cost → propose caps/quality filters (briefly).
Conclusion: Clear answer (“to a large extent”) + synthesis; no new ideas.

Step 3 — Write high-impact paragraphs

Keep the introduction lean: one paraphrase sentence and one thesis sentence are enough. Make your thesis explicit about extent (“I largely agree …”). Start each body paragraph with a topic sentence that directly answers the question and names the reason. Follow with a clear mechanism that shows how the policy causes the outcome (e.g., removing tuition lowers financial barriers → enrolment rises → skills base expands). Add a micro-example that sounds realistic but brief (country or cohort). Use precise academic verbs such as “facilitates,” “deters,” “redistributes,” and “yields.” If you include a counterpoint, make it short and structural (e.g., “funding pressure”) and then re-centre your stance with a remedy (e.g., progressive taxation, caps for non-priority programmes). Avoid moralising; prioritise causal logic and clarity. Keep sentences varied but controlled; prioritise accuracy over flair. End each paragraph with a link-back that ties the idea to your thesis. Conclude by restating extent and synthesising the two reasons in new words, avoiding fresh claims.

Example Box — High-impact Sentences

Thesis (balanced agree): “I largely agree that tuition should be free at the point of use because it widens access and strengthens the skills base, provided funding is safeguarded.”
Topic sentence (Body 1): “Removing tuition fees primarily expands access for capable students from low-income families.”
Micro-example: “For example, after fees were reduced, first-generation enrolments rose in several regional universities.”
Conclusion line: “Overall, while financing must be handled carefully, the mobility and growth gains justify broad tuition relief.”

Step 4 — Language, coherence, and accuracy

Choose topic-specific lexis that signals precision: “means-testing,” “progressive taxation,” “human-capital formation,” “opportunity cost,” and “capacity constraints.” Use cautious hedging (“tends to,” “is likely to”) where evidence would be needed. Maintain cohesion with pronoun reference and synonyms to avoid repetition (“this policy,” “such funding”). Keep one clear idea per paragraph and delete sentences that drift from your line of argument. Check subject–verb agreement, article use with abstract nouns, and comma placement in complex sentences. Prefer active, declarative clauses for clarity. Balance linkers; overusing simple connectors can sound mechanical. Ensure your word choice is formal and neutral. Proofread for consistency in terms (use either “tuition-free” or “fee-free,” not both). Verify that every topic sentence answers the question and that each paragraph ends by linking back to your stance. In the final minute, scan for grammar slips and confirm your conclusion states the extent unambiguously.

Band 6 — Sample Answer

Question: Governments should invest more in public transport than in building new roads. To what extent do you agree or disagree?

In many countries, traffic and pollution are daily problems, and policy makers must decide where to put limited funds. Some people think that building more roads is the fastest solution, while others argue that public transport deserves higher priority. I mostly agree that governments should invest more in public transport because it can reduce congestion and protect the environment, although some road projects remain necessary in rural areas.

The first reason to focus on public transport is congestion. When cities add new lanes, drivers often return to the road until it becomes crowded again, so the relief is temporary. By contrast, frequent buses, safe trams and reliable metro lines can move large numbers of people in one go. If services are clean, on time and affordable, commuters are more likely to leave their cars at home. For example, when my city increased bus frequency during peak hours, many office workers switched from driving, and journeys became more predictable. This shows that quality public systems can give people a practical alternative to private cars.

Another reason to prioritise public transport is the environment. Cars create air pollution and greenhouse gases, especially when they are stuck in traffic. A single electric tram or a full bus can replace dozens of cars, which helps to cut emissions. Admittedly, public transport is expensive to build and does not reach every village. In remote areas, maintaining and improving roads is still important for farm access, emergency services and basic trade. However, in most towns and cities, improved and integrated public transport will bring wider, longer-term benefits than pouring concrete into more road capacity.

In conclusion, I largely agree that governments should put more money into public transport rather than new roads. Better services reduce congestion and pollution and give people a real choice, while targeted road upgrades can be kept for places that truly need them.

  17. Overall control is adequate for Band 6, though more precise lexis and complex sentences could improve it.

Band 7 — Sample Answer

Whether to expand road networks or strengthen public transport has become a defining policy choice for modern cities. I largely agree that greater investment should go to public transport because it delivers more reliable capacity and fairer access, although strategic road upgrades remain sensible for freight and remote regions.

Public transport provides scalable capacity. Adding general-purpose lanes often triggers extra car use until queues return, so expensive road schemes can offer only short-lived relief. By contrast, high-frequency buses, bus-priority corridors, and metro lines can move far more people per hour in the same space. When services are frequent, integrated and ticketing is simple, commuters experience shorter, more predictable journeys. For example, after a neighbouring city rolled out bus-priority signals and an express corridor, peak-hour travel times fell for both bus users and drivers because buses no longer blocked junctions unpredictably.

Prioritising public transport is also fairer and greener. Low-income workers, students and older residents depend on affordable services; better coverage enables them to reach jobs and education without owning a car. In environmental terms, shifting travellers from private vehicles to shared modes reduces emissions and improves air quality. Admittedly, roads still matter: rural routes need maintenance, and logistics require dependable highway links. Even so, most urban congestion stems from commuter traffic, and the most cost-effective way to address it is to offer a credible alternative to driving rather than repeatedly widening roads.

In sum, governments should channel the larger share of funds into public transport because it expands capacity efficiently and supports equity and climate goals. Limited road investment should continue where it clearly enables freight and connects isolated communities.

Band 8+ — Sample Answer

Deciding between pouring funds into new roads or modern public transport is not merely a technical issue but a choice about the kind of city a society wants. I agree to a large extent that investment should prioritise public transport because it delivers superior marginal capacity and aligns with equity and climate objectives; nonetheless, targeted highway works remain justified for freight corridors and genuinely isolated communities.

From a capacity perspective, building additional general-purpose lanes often invites the very traffic it aims to disperse. As driving becomes temporarily faster, latent demand is activated and queues re-emerge. Mass transit, by contrast, scales without multiplying vehicles: a high-frequency, reliable network—whether bus rapid transit, light rail or metro—moves thousands of passengers per hour in the footprint of a couple of traffic lanes. When services are frequent, legible and integrated with seamless ticketing, travellers optimise for reliability, not only for speed. Brief, targeted measures such as bus-priority signals and dedicated corridors further stabilise journey times, improving conditions for remaining drivers as well.

Public transport also advances distributional and environmental goals. Affordable, accessible networks widen participation in employment and education for households that cannot sustain car ownership, while cleaner fleets and mode shift cut urban emissions and noise. Critics argue that rail lines are capital-intensive and that cities still need roads. Both points are valid, yet neither undermines the central claim: the most cost-effective path to reducing urban congestion is to make the alternative to driving competitive, while reserving road budgets for maintenance, safety upgrades and freight reliability. In other words, the priority is not “no roads” but “no more generic urban widening” unless paired with measures that limit car dependency.

Overall, governments should devote the greater share of transport budgets to frequent, integrated public transport, complemented by selective road projects that protect logistics and connectivity where transit cannot substitute. This portfolio best addresses capacity, fairness and environmental constraints.

Why this Band 8+ answer is good — Step-by-step
  1. The thesis states the extent of agreement and frames the policy trade-off precisely.
  2. Paraphrasing is sophisticated and avoids lexical repetition from the prompt.
  3. Body 1 articulates a causal chain (lane expansion → latent demand → renewed congestion).
