How to learn IELTS: a complete study guide

IELTS is not a test of intelligence or of how long you have studied English. It is a test of four specific skills, marked against published band descriptors, and it rewards a method. This guide explains what the exam actually measures, how the band score is worked out, how long preparation really takes, and exactly how to practise each of the four papers — with a twelve-week plan you can start today.

Written by the team behind OpusDesk IELTS, a practice site where every answer is explained by quoting the line of the text that proves it. Free tests for all four skills are linked throughout, and no account is needed to start.

1. What IELTS actually tests

IELTS — the International English Language Testing System — is a four-paper exam produced by the British Council, IDP Education and Cambridge University Press & Assessment. There is no pass or fail: you receive a band from 1 to 9 for each paper and an overall band for the whole exam.

The four papers are fixed in order and timing, and the whole test is taken in one day, with the Speaking paper sometimes on a different day.

Two consequences follow from that table, and they explain most of the advice in this guide. First, Reading and Writing are the papers where candidates lose the most marks, because they punish both language and method: slow readers run out of time, and essays that answer the wrong question cannot score well however elegant the English. Second, Listening and Speaking are marked on the same scale as the others, so an hour spent improving note-taking or fluency buys the same band-points as an hour of grammar.

2. Academic or General Training?

Choose the version your destination requires — you cannot switch after booking, and mixing them up is the most expensive mistake in IELTS.

• IELTS Academic is for university admission and for professional registration. Its Reading passages are academic articles, and Writing Task 1 asks you to describe a chart, table, diagram, map or process.
• IELTS General Training is for migration, work experience and secondary education. Its Reading texts are everyday material — notices, advertisements, handbooks — and Writing Task 1 is a letter, formal or informal.

The Listening and Speaking papers are identical in both versions, so those two papers can be prepared with the same material and the same method regardless of which test you sit.

3. How the IELTS band score is calculated

Each paper is marked out of 9 in half-band steps, and then the four scores are averaged. The average is rounded to the nearest half band, with .25 rounding up to .5 and .75 rounding up to the next whole band. So 6.5, 6.5, 5.0, 5.0 averages to 5.75 and reports as 6.0; 7.0, 7.0, 7.0, 6.5 averages to 6.875 and reports as 7.0.

For Reading and Listening, the raw mark out of 40 is converted to a band through a table that changes slightly from one test version to another. As a rough guide, around 30 out of 40 is band 7.0 and around 23 out of 40 is band 6.0 for Academic Reading, with Listening conversion usually a mark more generous. Because the conversion shifts, test yourself with full papers of 40 questions rather than extrapolating from a ten-question quiz.

4. What score do you need?

Requirements are set by the organisation, not by IELTS, so always check the exact wording of the institution or authority you are applying to — and check whether they require a minimum in each paper as well as an overall band. That second condition is the one people miss: an overall 7.0 made of 7.5, 7.5, 7.5 and 5.5 fails a requirement of "7.0 overall with no band below 6.5".

Convert your target into a study target: if you need 7.0 overall, you almost certainly need 30+ correct answers in Reading and Listening, a Writing answer that answers the question fully with clear paragraphing, and a Speaking performance that keeps going without long pauses.

5. How long does it take to learn IELTS?

Anyone promising a band 8 in a fortnight is selling something. Progress depends on your starting level and on how much of your study time is spent answering questions under exam conditions rather than reading about the exam.

The pattern in that table is the useful part: the last half band is always the slowest, because it is bought with accuracy at the top end — fewer spelling errors, more precise vocabulary, better paragraph logic — rather than with new knowledge.

6. A 12-week IELTS study plan

The plan below assumes about two hours a day, six days a week, with one rest day. It is deliberately front-loaded with diagnosis and back-loaded with full mock tests, because practising a paper you have not diagnosed is how people spend three months becoming better at their weakest habit.

If you have less time than that, keep the shape and compress the middle: diagnosis, method, timed practice, review. Cut the reading about IELTS before you cut the practice papers.

7. How to improve IELTS Reading

Academic Reading gives you three long passages and 40 questions in 60 minutes — roughly 90 seconds per question including reading time. Nobody finishes by reading carefully and then answering; the mark comes from a repeatable loop.

1. Survey (2 minutes). Read the title, the first sentence of each paragraph and any headings. You are building a map, not understanding every word.
2. Read the questions first, in order. Most question sets follow the order of the passage. The exception is matching headings and matching information, which you should treat as a separate pass.
3. Answer by locating, not by remembering. Find the sentence the question paraphrases, and underline it. If you cannot point at a line, you have not answered the question, you have guessed.
4. Write the answer on the sheet immediately. There is no transfer time in Reading; leaving answers to the end is a common way to lose ten marks.
5. Review in a fixed order. Timing first (did you finish?), then question-reading errors, then vocabulary, then spelling and plurals. The cause matters more than the score.

True, False or Not Given — the three-way decision

This is the question type that costs the most marks, and the rule is simple once stated properly. True means the passage supports the statement. False means the passage states the opposite. Not Given means the passage says nothing either way — the information is simply absent. A statement is not False because it is unproven; it is False because the text contradicts it. Practising that distinction, with the evidence line written down for every answer, is worth more than any tip list.

Practise with a free full Academic Reading test — three passages, 42 questions, and an explanation for every item that quotes the line that proves it.

8. How to improve IELTS Listening

Listening is the paper where the fastest gains are available, because most lost marks come from three mechanical faults: losing your place, misspelling the answer, and writing two words where one is allowed.

• Use the pause before each part to read ahead. Underline the words that tell you what kind of answer is coming: a number, a name, a time, a place.
• Expect the correction. Speakers routinely say one thing and then change it — "on Tuesday… sorry, Wednesday". The second version is the answer.
• Spell it correctly. A correct word spelled wrongly scores zero. Keep a personal list of words you have misspelled twice, and dictate them weekly.
• Check the word limit. "NO MORE THAN TWO WORDS AND/OR A NUMBER" is part of the question. Writing three words scores zero even when the words are right.
• Never stop to think. If you miss one, let it go and rejoin at the next question. One lost mark is cheaper than four.

The four parts have different shapes: Part 1 is a conversation about an everyday transaction, Part 2 a monologue giving information to a group, Part 3 a discussion between two or more students and a tutor, Part 4 an academic lecture. Practise each with a free Listening test that includes the full transcript, so you can check not only whether you were right but which words you misheard.

9. How to improve IELTS Writing

Writing is the paper most candidates underestimate and the one where band scores stall. It is marked on four criteria — Task Response, Coherence and Cohesion, Lexical Resource, and Grammatical Range and Accuracy — and Task 2 carries twice the weight of Task 1.

Task 1 (Academic): the four-paragraph shape

Spend 20 minutes and write at least 150 words. The reliable shape is: an introduction that restates the task in your own words without copying it; an overview that names the two or three biggest features — this is the paragraph examiners look for and the one candidates skip; then one or two paragraphs of detail, grouped logically rather than listed. Use the data to support comparisons ("twice as many", "just under half", "the only category that fell"), not to recite every number.

Task 2: answer the question that was asked

Spend 40 minutes and write at least 250 words. Before writing, decide two things: what the question type is (opinion, discussion, problem–solution, two-part question), and what your position is. Then plan four or five paragraphs: introduction with a clear position, two or three body paragraphs each making one point and supporting it, and a conclusion that restates the position without adding new ideas.

Half of all Task 2 losses are task-response losses: the essay never states an opinion when one was required, discusses only one side of a two-sided question, or answers a related but different question. Before you worry about vocabulary, check that every part of the prompt has been answered.

Our writing section marks a draft against the same checklist an examiner would use for structure — length, paragraphing, repetition, linking, and whether the question was addressed — using rules rather than an AI guess, so you can see exactly which rule your draft breaks. Start with Task 1 and Task 2 and read the guidance for each prompt before you write.

10. How to improve IELTS Speaking

Speaking lasts 11–14 minutes across three parts: an introduction and interview, a two-minute long turn from a cue card after one minute of preparation, and a discussion that becomes more abstract. You are marked on fluency and coherence, lexical resource, grammatical range and accuracy, and pronunciation.

• Fluency beats accuracy in Part 2. A candidate who speaks for two minutes with small errors scores higher than one who speaks perfectly for forty seconds and stops.
• Use the preparation minute properly. Write four or five keywords, one per bullet on the cue card, not full sentences. Full sentences make you read instead of talk.
• Structure the long turn. Past, detail, feeling: what happened, one concrete detail that shows vocabulary, and how you felt about it.
• In Part 3, answer the question that was asked. Give a direct answer, then a reason, then an example or a contrast. Two clear reasons beat five vague ones.
• Record yourself and count the pauses. Anything longer than three seconds in the middle of an answer is a fluency mark you can hear.

The speaking section includes cue cards, follow-up question chains for Part 3, a preparation and speaking timer, and a statistics view that reports your speaking rate, your pauses and your filler words from a recording — measurements, not opinions, because no rule-based system can grade pronunciation honestly.

11. Vocabulary and grammar: the unplanned hours

Most candidates plan papers and forget the two things that decide whether their language is band 6 or band 7: topic vocabulary and error-free complex sentences.

• Learn words in topic sets, not alphabetically. Twenty words about the environment are worth more than a hundred random ones, because Reading and Writing both recycle topics.
• Record the word with its collocations. "A significant rise", "a sharp fall", "address a problem", "a long-term consequence" — the partners are what examiners recognise as range.
• Review on a schedule. Spaced repetition matters more than the number of new words per day. A hundred words reviewed five times beats five hundred seen once.
• Fix grammar by rule, not by feel. Keep the same error notebook for grammar: articles before singular countable nouns, subject–verb agreement, tense consistency inside one paragraph, and the comma splice. Four rules cover most band-6 grammar losses.

Our vocabulary trainer uses spaced repetition with a daily word, and the grammar section covers twelve lessons, each with a worked example and the classic error it prevents.

12. Seven habits that keep people at band 6

1. Practising without marking. Unmarked practice teaches you your current habits. Always mark, and always write the cause of the error.
2. Reading about IELTS instead of doing it. Tips are cheap; timed papers are what move the score.
3. Ignoring the word count. Under-length Writing answers are penalised before content is considered.
4. Memorising whole essays or answers. Examiners are trained to spot it, and it collapses the moment the question changes.
5. Treating Not Given as False. The single most expensive misreading in Reading.
6. Never listening to your own speaking. Most fluency problems are invisible until you hear the recording.
7. Stopping practice two days before the test, or cramming the day before. Stamina is part of the exam: four papers in one day is a physical task.

13. Free and official resources

Use a small number of sources properly. The official bodies publish the format, the band descriptors and free sample papers, and those are the only materials that define the exam.

• IELTS.org — the official site, with the format, band descriptors, test dates and free sample questions.
• British Council — IELTS preparation — free practice tests, a preparation course and guidance on scoring.
• IDP — IELTS preparation — sample tests and webinars from the other co-owner.
• Cambridge English — the body that writes the papers.
• OpusDesk IELTS — free full tests for Reading, Listening, Writing and Speaking, with every answer explained by quoting the text.

One warning about social media advice: any tip that promises a band without practice under time pressure is describing luck, not method.

14. Test day: what actually happens

• Bring the right identity document. It must be the same one you registered with, and it must be current. Check the rules for your test centre in advance.
• No electronics in the exam room. Phones must be switched off and handed in or left outside; a phone that rings can void your result.
• Listening first, then Reading, then Writing, with no breaks in between for the paper-based test. Plan your energy accordingly.
• Writing by hand or by computer — computer-delivered tests give you a word count and easier editing, and some people gain a band in Writing purely from being able to revise.
• Speaking may be on the same day or up to a week later, and it is a conversation with a trained examiner, not a machine. You can ask the examiner to repeat a question once.
• Results arrive in about 13 days for paper-based tests and 3–5 days for computer-delivered, and the report is valid for two years for most purposes.

16. About this guide and this site

This guide exists to answer one question — how to learn IELTS — in the order the decisions actually have to be made: what the exam measures, what score you need, how long it takes, what to practise each week, and how to tell whether the practice worked. OpusDesk IELTS is a practice site built around one rule: no answer is explained without quoting the line of the passage or transcript that proves it. Every reading and listening question carries the evidence sentence and the reason the correct option is correct; writing is checked by explicit rules rather than by an AI opinion; speaking reports measurements — rate, pauses, fillers — and says plainly that pronunciation cannot be graded by a rule.

The first test of each skill is free and complete: three passages and 42 questions for Reading, four parts and 40 questions for Listening, both writing tasks, and a full three-part interview. The paid tier adds the remaining twelve tests per skill and annotated model answers. Nothing is graded by an AI, and no account is required to try the free tests.

Study material on this site is written for the site rather than copied from published papers, and the exam content is deliberately kept in English only — the test is in English, so the practice is too.
