In Part 4 key word transformations, the candidate writes a correct-looking paraphrase but alters the given keyword or leaves it out entirely (for example, turning 'give' into 'gave' or paraphrasing it as 'provide'), so the answer scores zero however good the grammar is.
Under time pressure candidates focus on building the second sentence and treat the keyword as a hint about meaning rather than as a fixed, compulsory component they must copy.
What to do instead
Write the keyword first, exactly as printed and in capitals if you like, then build the rest of the sentence around that exact string. Before moving on, verify three things: the keyword appears character-for-character, both sentences mean the same thing, and the total is between three and six words.
In Part 3 word formation, the candidate supplies the first derivative that comes to mind (often the wrong word class) and ignores negative prefixes, producing 'success' where 'unsuccessful' is needed or an adjective in a slot that requires a noun.
Candidates read the root word and free-associate a family member rather than analysing the grammatical slot the gap occupies in the sentence frame.
What to do instead
Cover the root word, read the whole sentence and label the gap grammatically first: after an article and before 'of' it is a noun; before a noun it is an adjective; after a preposition it may need -ing. Only then attach the suffix, and always test whether the meaning needs un-, in-, im-, dis- or -less.
In Part 2 open cloze, candidates leave gaps blank or guess long content words, because the missing word 'seems too simple' (it, such, much, there, which, despite).
They expect a vocabulary test and hunt for meaning-bearing words, not realising Part 2 tests grammatical and cohesive devices.
What to do instead
Before guessing, name the grammatical job of the gap: is a relative pronoun, article, quantifier, preposition, auxiliary or linking adverb needed? Train on the high-frequency set (which, that, as, such, so, much, enough, despite, although, whether, it, there) and never leave a gap empty - a plausible grammar word scores more often than a blank.
In Writing Part 1, the candidate lifts the three bullet notes almost verbatim into the essay and stops at around 180 words, with no development, no example and no link between the ideas.
Copying the notes feels efficient under exam pressure and candidates lose track of the 220–260 word target, having practised mainly at B2 length.
What to do instead
Plan one paragraph per bullet, and for each one write a topic sentence in your own words plus one justification or example that is not in the notes. Add a short introduction and a conclusion with your own fourth idea. Count words in the exam and aim for about 240, which forces development.
In Writing Part 2 the candidate produces a text with the right content but the wrong genre signals - a review with no evaluation or recommendation, a proposal with no headings or expected outcomes, a letter opening 'Dear Sir or Madam' when the task names a friend.
Candidates prepare content and vocabulary but never memorise the conventional layout and register of each text type, and exam tasks look similar at a glance.
What to do instead
Build a one-page checklist per genre (review: description, evaluation, recommendation; proposal: headings, current situation, suggestions, benefits; report: introduction, findings, conclusion) and rehearse it. In the exam, underline the target reader and the genre in the rubric and check both against your plan before writing.
The candidate fills the writing with memorised 'advanced' formulae - 'It is a widely acknowledged fact that…', 'Last but not least…', 'In today's fast-paced world…' - regardless of the task, and repeats the same linker in every paragraph.
Formulaic chunks feel like a shortcut to a higher register, and candidates believe complexity is scored on the presence of impressive-looking phrases.
What to do instead
Cut any phrase that would survive being pasted into a different task. Replace it with a plain, accurate sentence carrying real content, and vary linking with devices tied to logic: 'whereas' for contrast, 'provided that' for condition, 'the main drawback being' for concession. Accuracy and range of structure score; decoration does not.
In Listening Part 2, the candidate writes a full phrase or a verbatim chunk from the recording, breaking the word limit or producing an answer that does not fit the grammar of the prompt (writing 'to reduce costs' after 'the aim of the scheme is ___').
Candidates transcribe while listening and do not re-read the stem as a completed sentence, and they are unsure whether the limit is one or two words.
What to do instead
After the recording stops, use the 45-second check to read each answer back inside the stem for grammar and to count words, deleting articles or auxiliaries that are not needed. Answer in the form the stem demands (noun phrase for 'the aim is', bare infinitive after 'in order to').
In Listening Parts 3 and 4, the candidate picks an option because a word from it was just heard on the recording, and commits before the speaker finishes or before a contrast marker such as 'but', 'actually' or 'having said that'.
Lexical matching is fast and feels safe, and distractors are deliberately built from words spoken earlier in the extract, while the real answer comes from the final stance.
What to do instead
Treat any option containing an exact word from the audio as a suspect until the speaker finishes the turn. Note hesitation and reversal markers as signals that the answer is about to change, and delay marking the answer until you hear the speaker's conclusion or the next question starts.
In Speaking Part 2, the candidate describes photo one in full, then photo two in full, runs out of time and never answers the question printed above the photographs.
Describing is easier than comparing, and candidates treat the two photos as two separate mini-descriptions rather than one comparative task.
What to do instead
Structure the minute explicitly: 20 seconds on a direct comparison of two or three points using 'whereas', 'unlike', 'both', 'the main difference being'; 25 seconds on speculation ('they might be…', 'it looks as though…'); the last 15 seconds answering the question directly, starting with 'On balance, I'd say…'. Practise with a timer until the shape is automatic.
In Speaking Parts 3 and 4, candidates answer the examiner's questions individually and in single sentences, so no discussion happens and there is too little language to assess; Part 1 answers are similarly one clause long.
They interpret the interaction as a test of personal answers rather than a collaborative task, and short answers feel safer than making errors.
What to do instead
In Part 3, respond to your partner before adding your own view ('You mentioned cost - I'd add that…') and ask at least one question to keep the exchange going. In Parts 1 and 4, use a two-part answer: a direct response plus a reason or example, which reliably gives the examiner enough range to reward.
