The theme most damaged by preparation — memorised statistics are obvious and score badly.
Whether you can discuss responsibility. The questions are rarely about the science; they are about who should act, at what cost, and whether individuals matter against governments and industry.
Longer answers than Part 1 — thirty to forty-five seconds each. The examiner may disagree with you, which is the format working as intended.
Part 3 is scored on whether you can generalise and speculate without overstating. These are the phrases that do that work in this particular area.
a drop in the ocean
for individual action against the scale of the problem
the onus is on
formal and precise for responsibility
there's a trade-off between
the key construction for growth versus environment
incentivise
for policy that changes behaviour without banning
in the grand scheme of things
for putting a small measure in proportion
it's a start
concise concession about partial measures
A wrong or vague statistic is worse than none, and a memorised one flattens your fluency the moment you reach for it. Explain a mechanism instead — that is genuinely your English on display.
Watch the moves, not the opinions — take a position, hedge it as far as you actually believe it, support it, and give the strongest objection its due. Your views can be the opposite of these and score the same. A memorised Part 3 answer is more obvious than a memorised Part 1 one, because the examiner follows up on what you just said and a script cannot survive the follow-up.
Governments, overwhelmingly, and I say that as someone who does the recycling. Individual action matters mainly as a signal — it changes what feels normal, and that shifts what's politically possible. But the arithmetic is that a household's entire annual footprint is a rounding error against one industrial decision. I think the emphasis on personal responsibility has been convenient for the people who'd otherwise be regulated, and it's made a lot of people feel guilty about things that were never going to be decisive.
Why it worksNames a position, concedes the value of the opposite, then explains why the framing itself is suspect — three levels of argument in one answer.
Concerned in the abstract, yes, and much less willing to accept the specific costs. If you ask whether it matters, almost everyone says yes. If you propose something that makes driving or flying more expensive, the same people object, and I'd include myself some of the time. I don't think that's hypocrisy exactly — it's that the costs are immediate and personal and the benefits are distant and shared, which is a structure humans handle badly.
Why it worksIdentifies a gap between stated and revealed preference, includes itself in the criticism, and then explains the gap structurally rather than moralising about it.
The theme where candidates most reliably slip back into Part 2 and start telling stories about their own family.
The theme with the most room to say something the examiner has not heard before, and the least prepared by most candidates.
Contemporary and opinion-heavy, and the theme where an unsupported claim is most likely to be challenged.
Responsibility and behaviour change, not medicine — no specialist knowledge is needed or wanted.
Abstract and comfortable to overgeneralise about, which is exactly where this theme catches people.
Concrete, policy-shaped, and the theme most improved by naming an actual place.
Oliver pushes back in Part 3 the way a real examiner does — not to catch you out, but because holding a position under mild pressure is exactly what is being scored. That is not something you can rehearse against a list of questions. The first test is free.
