The last week before your IELTS: what actually moves your band

Search for advice on the week before your IELTS and you will mostly find pages that tell you to stay calm, revise vocabulary and get a good night's sleep. Some of them are titled "complete guide" and run to a couple of hundred words.

Here is the more useful framing. In the last week you cannot meaningfully improve your English. You can, however, stop losing marks you are currently losing — and those are different problems with different fixes.

We built the engine that scores speaking and writing answers on Hilingo, so this is written from the marking side: not what to study, but where bands actually leak in the final week and on the morning itself. For anything official — ID rules, centre procedures, what your specific test day looks like — the authority is ielts.org and your test centre, not a blog.

The one thing to do first

Sit one full mock under real timing, in one sitting, before you do anything else this week.

Not a section. Not "the reading bit while I have half an hour". The whole thing, timed, in the order the real test runs it. Almost everyone discovers their problem is not the skill they have been revising.

The reason is arithmetic: your overall band is dragged down by your weakest section, and most people spend the final week on the section they enjoy. A timed mock tells you which one to spend the remaining days on. Guessing gets it wrong more often than not.

Where marks actually leak, by section

Writing: the criteria are not what most people revise

IELTS writing is marked on four criteria, weighted equally: task achievement (task response in Task 2), coherence and cohesion, lexical resource, and grammatical range and accuracy.

Read that list again, because it explains the single most common late mistake. Three of the four criteria have nothing to do with vocabulary. Yet "learn more advanced words" is the most common last-week plan, and it often makes things worse — an unfamiliar word used slightly wrong damages lexical resource rather than helping it.

The cheaper wins in the final week:

• Answer the question that was asked. Task response is a whole criterion. An elegant essay that drifts off the prompt loses a quarter of the available marks before grammar is even considered.
• Write enough. Task 1 asks for at least 150 words and Task 2 at least 250. Under-length is penalised directly, and running short is entirely avoidable. Know what 250 of your own words looks like on the page.
• Cover every bullet. General Training Task 1 gives you three bullet points. Each one is part of the task. Missing one is a self-inflicted band.
• Leave two minutes to read it back. Not to rewrite — to catch the article, the plural and the tense slip that cost grammatical accuracy.

Speaking: fluency beats complexity, and silence is expensive

Speaking is marked on fluency and coherence, lexical resource, grammatical range and accuracy, and pronunciation.

The late mistake is reaching for impressive structures and stalling halfway through. A simple sentence delivered fluently scores better than a complex one abandoned mid-clause. In the final week, practise keeping going rather than adding constructions.

Two specific things:

• Extend every answer. One-sentence answers give the examiner nothing to assess. Add a reason or an example to each, as a reflex.
• Do not memorise answers. Rehearsed paragraphs are audible — the rhythm changes — and they fall apart the moment the examiner asks something adjacent. Prepare ideas for common topics, not sentences.

Listening: the marks you lose are spelling marks

Listening content is rarely the problem for people already near their target band. Transcription is. A correct answer spelled wrong is wrong, and so is a plural you did not hear.

In the final week, practise writing answers down while listening rather than after, and check the spelling of the categories that recur: days, months, countries, common names.

Reading: the last passage is where bands die

Reading is a time management test as much as a comprehension test. The predictable failure is spending too long on the second passage and arriving at the hardest one with eight minutes left.

Give yourself a hard per-passage limit and move on when it expires, even mid-question. An unanswered question and a wrong one score the same, so there is never a reason to leave a blank.

The 48 hours before

• Stop taking full mocks. Past a point they measure fatigue rather than ability. Review what your last mock told you instead.
• Confirm the logistics properly. Test centre address, reporting time, and the identity document you registered with — the same one, not a different valid document. Centres are strict about this and it is the most avoidable way to lose a test fee.
• Check what you may take in. Personal items are generally not allowed in the test room and are stored outside. Requirements vary by centre and by format, so confirm yours rather than assuming.
• Sleep. This is the one piece of generic advice that survives scrutiny, because listening and reading both degrade sharply when you are tired.

On the day

Arrive early enough that arriving is not itself stressful. Expect identity checks and a wait.

Two things worth knowing before you are in the room:

• You cannot go back to a section once it is done. Budget within a section, not across them.
• A bad section is not a bad test. Your band is calculated across four sections. Candidates lose marks in sections three and four by continuing to think about section two. Finish each one and close it.

What will not move your band this week

Being honest about this saves you the time:

• Learning new vocabulary lists. The words will not be automatic enough to use accurately under pressure.
• Memorising template essays. Examiners recognise them, and they push you toward answering a question you were not asked.
• Reading about the test instead of sitting it. There is a point at which more articles — this one included — stop helping and one more timed mock starts.

Find the section that is actually costing you

Everything above depends on knowing which of your four sections is weakest under real timing, which is the one thing a week of revision cannot tell you.

Hilingo gives you one full scored mock free, with no card. Full length, real timers, and our own engine scores every writing and speaking answer against the criteria above — per task and per question, with the reason an answer was wrong and the evidence quoted from the passage or transcript. That is what tells you where to spend the days you have left.

Frequently asked questions

How many mock tests should I do in the last week?

One full timed mock early in the week, and then stop. After that, more mocks measure fatigue rather than ability, and the time is better spent reviewing what the first one showed you. The mock is a diagnostic, not the training.

Should I learn new vocabulary the week before IELTS?

Generally no. Vocabulary is one of four equally weighted writing criteria, and a word learned days ago is rarely automatic enough to use accurately under exam pressure. Using it slightly wrong lowers lexical resource rather than raising it. Accuracy with words you already own scores better.

What should I do the day before the test?

Confirm your centre address, reporting time and the exact identity document you registered with; check what your centre allows into the room; and sleep. Do not sit a full mock — tiredness costs more marks on the day than one more practice can earn.

Can I improve my IELTS band in one week?

You can usually recover marks you are currently losing — running under the word count, missing a bullet, leaving reading questions blank, one-sentence speaking answers. You are unlikely to raise your underlying English. Aim at the first category, because that is where a week actually pays.

What happens if one section goes badly?

Your band is calculated across all four sections, so one weak section is not a failed test — but continuing to think about it is how candidates lose the sections that follow. Close it and move on.
