The method behind every band

The Ladder MethodPhương pháp Bậc Thang

Reading and Writing are not two subjects. They are one ladder of ideas — climbed in opposite directions.

Learn the Ladder Method — the full course →Ten short lessons turn this idea into a skill: worked examples, practice you check yourself, and a link into the drill for every move.

Writing climbs up

You start with a plain idea — often first thought in Vietnamese — and rebuild it rung by rung. Band 6 links it in one clear sentence; Band 7 tightens it with subordination and precise vocabulary; Band 8 makes it flexible and natural; Band 9 controls every word. The climb is rarely about piling on clauses for their own sake — it is about precision: the exact structure and the right word, not the biggest one. You are not hunting for impressive vocabulary; you are moving one idea to a higher rung.

Reading climbs down

A hard passage is just Band-8/9 sentences you must climb DOWN — strip each dense sentence back to the plain rung underneath. Then most multiple-choice options are rungs too: the answer sits on the same rung as the text; distractors sit one rung too high (a claim stronger than the text — "all", "only", "always") or one rung too low (weaker or vaguer than the text). And watch for the last kind: some options sit off the ladder entirely — true-sounding, but never actually stated.

One ladder, worked both ways

The same idea — “cars cause pollution, so cities limit them” — at four rungs. Writers read this bottom-to-top; readers read it top-to-bottom.

Band 9
Faced with mounting evidence that private vehicles are a primary driver of urban air pollution, many municipalities have moved to curb their use.
The move up from Band 8: the cause is folded into a participial opener ("Faced with mounting evidence that…"), the noun phrase becomes exact ("a primary driver"), and the verb turns formal ("curb"). Nothing is bolted on for show — every word earns its place. This is a wide range with full control.
Band 8
As private vehicles are one of the leading contributors to urban air pollution, a growing number of governments have moved to restrict their use.
The move up from Band 7: the subordinator sharpens ("Because" → "As"), the noun phrase widens ("a major source" → "one of the leading contributors"), and "cars" lifts to "private vehicles". A wide range, used accurately and naturally — only Band 9's density and control lie above it.
Band 7
Because cars are a major source of air pollution in cities, many governments have introduced measures to restrict their use.
Subordination ("Because…"), a precise noun phrase ("a major source"), the present perfect, and "restrict their use" instead of "limit them". The register is now academic and the cause–effect is explicit.
Band 6
Cars cause a lot of pollution in cities, so many governments are trying to limit them.
The entry rung of the exam range — a full compound sentence joined by a real linker ("so"), which a Band-6 writer can reliably produce. It communicates clearly, but "so" only coordinates (two equal clauses set side by side), the vocabulary is everyday ("a lot of", "trying to limit"), and the cause–effect is left loose. The first move up is not more words — it is turning that "so" into genuine subordination ("Because…") and making the vocabulary precise.
Now climb the same rung down — reading

That was the climb up. Reading is the same ladder climbed down. Here is the Band-9 sentence exactly as it might sit in a passage — strip it back to the plain rung underneath, and the rungs sort the answer from the traps.

In the passage
Faced with mounting evidence that private vehicles are a primary driver of urban air pollution, many municipalities have moved to curb their use.
Climb down, one rung at a time
“Faced with mounting evidence that…” “Because there is more and more proof that…”
a participial opener is a cause in disguise
“private vehicles are a primary driver of urban air pollution” “cars are a main cause of city air pollution”
“many municipalities have moved to curb their use” “many city governments have started to limit them”
The plain rung underneath
Cars are a main cause of city air pollution, so many cities are starting to limit them.
— the exact rung a writer would start from.
Now map the options — which one does the passage support?
Q. Why have many municipalities moved to curb the use of private vehicles?
A. Growing evidence points to cars as a leading cause of urban air pollution.
Same rung — the answer
The plain rung in other words: the same claim as the text, said more simply.
B. Cars are the only cause of air pollution in cities.
One rung too high
“A primary driver” is not “the only cause”. Language stronger than the text — only, all, always — is the commonest trap.
C. A few officials suspect cars may have a small effect on air quality.
One rung too low
“Primary driver” has been watered down to “may have a small effect”, and “a few officials suspect” invents a source the passage never gives.
D. Maintaining cars in congested cities is expensive.
Off the ladder
It sounds plausible, but the sentence never says it. Some distractors aren’t on this ladder at all — out of scope / Not Given.

The rule, reusable on any question: you never needed outside knowledge about cars. The answer sits on the SAME rung as the text — the same claim in plainer words. Every trap is a rung the text never reaches: too strong, too weak, or simply not there.

Why this beats a template

A template gives you one frozen sentence to paste in. It cannot move — so the moment the topic shifts, it breaks, and examiners are trained to spot memorised scripts. A ladder is not a sentence; it is a move you can make on ANY idea. Learn the four rungs once and you can climb up (write) or down (read) any topic they throw at you. That is why we stopped selling templates and teach the ladder instead.
