Key takeaways
- The overall band is the average of four skills rounded to the nearest half band — an average of 6.25 becomes 6.5 in the official example.
- Listening and Reading each have 40 one-mark questions: Band 7 takes roughly 30 correct answers in Listening and in Academic Reading.
- General Training Reading needs more correct answers for the same band — 30 for Band 6 against 23 in Academic.
- Writing and Speaking are marked on four equally weighted criteria, with Task 2 weighted more heavily in Writing.
- Test day runs 2 hours 45 minutes: Listening about 30 minutes, Reading 60, Writing 60, Speaking 11 to 14 minutes.
- One Skill Retake is available for computer-delivered tests within 60 days, once per full test, and results are recommended as valid for two years.

Your IELTS band is not an opinion about your English. It is a known formula: the average of four skills rounded to the nearest half band, with Listening and Reading marked out of 40 questions (IELTS). Once you understand the formula, raising your score becomes a decision about where to spend your effort rather than luck on test day.
How is your band score calculated?
The scale runs from 0 to 9, and the overall score is "the average of the four section band scores rounded to the nearest half band". The rounding works in your favour: an average ending in.25 rounds up to the next half band, and one ending in.75 rounds up to the next whole band. The official example: 6.5, 6.5, 5.0 and 7.0 average 6.25, which becomes 6.5 (IELTS).
In practice this means half a band in a weak skill can lift your overall score by half a band, while a full band added to an already strong skill may move nothing. Always start with your two weakest skills.
How many correct answers does each band need?
Listening and Reading each contain 40 questions worth one mark, and these are the published average marks:
| Band | Listening | Reading (Academic) | Reading (General Training) |
|---|---|---|---|
| 5 | 16 | 15 | 23 |
| 6 | 23 | 23 | 30 |
| 7 | 30 | 30 | 35 |
| 8 | 35 | 35 | — |
Source: IELTS. Note the gap: General Training Reading needs more correct answers for the same band, because its texts are easier.
Writing and Speaking are marked against four equally weighted criteria. For Writing: task achievement or response, coherence and cohesion, lexical resource, and grammatical range and accuracy, with Task 2 carrying greater weight in the final mark. For Speaking: fluency and coherence, lexical resource, grammatical accuracy, and pronunciation (IELTS).
Academic or General Training: which should you book?
IELTS Academic is for people "planning to study in a country where English is spoken" and measures readiness for university-level work. IELTS General Training suits those migrating or studying below degree level and emphasises everyday social and workplace English. Listening and Speaking are identical in both versions; Reading and Writing differ (IELTS).
For a Saudi student heading to an Australian degree, Academic is normally the one. Still, do not book before reading the English requirements for your university and your specific program, because universities set their own scores. ANU, for instance, states it accepts IELTS, TOEFL iBT, Cambridge C1 Advanced and PTE Academic, and refers applicants to its policy and program requirements for the score itself (ANU).
How long does test day take?
| Section | Duration |
|---|---|
| Listening | approximately 30 minutes |
| Reading | 60 minutes (including transfer time) |
| Writing | 60 minutes |
| Speaking | 11 to 14 minutes |
| Total | 2 hours and 45 minutes |
Source: IELTS. Knowing these timings matters: practise against the clock from the start, because untimed practice produces test-day surprises.
A practical plan for each skill
Listening
Listen once only, as in the real test, then mark your answers, then replay with the transcript to find exactly where the information slipped past. Watch two recurring traps: the speaker correcting themselves ("no, Tuesday"), and word limits on answers. Make your goal a number — if you are on 23 correct and want Band 7, you need seven more correct answers, not a vague improvement.
Reading
The problem in Reading is usually time, not comprehension. Split the hour across the three passages in advance, and start with question types that follow the order of the text. Do not read the whole passage first; read the question, then locate it. In True/False/Not Given, judge only what the text says, never what you happen to know.
Writing
Task 2 carries more weight, so start there if time is tight. Write a three-line plan before you write: your position, two reasons, and an example for each. In Academic Task 1, describe the overall trend first and then the telling figures, rather than listing every cell in the table. Then audit against the four criteria: did you actually answer the task, do your paragraphs connect, is your vocabulary varied without straining, are your sentences accurate?
Speaking
Two-word answers cost you fluency, and memorised answers are obvious immediately. Train a three-part structure: direct answer, reason, personal example. In Part 2, use the preparation minute for four keywords rather than full sentences. Pronunciation is its own criterion: clarity and intonation matter more than imitating a particular accent.
Common mistakes that cost half a band
- Practising without a timer, so the plan collapses on test day.
- Forgetting answer transfer in paper-based Listening, or exceeding the word limit.
- Memorised introductions in Writing, which do not count as your own productive language and do not address the task.
- Working on your strongest skill because it is enjoyable, when the formula rewards lifting the weakest.
- Resitting the whole test a week later without changing how you study.
Retake one skill, or the whole test?
IELTS One Skill Retake lets you retake a single section instead of the full test, with conditions: your original test must have been IELTS on computer at a centre offering the service, you must book and take the retake within 60 days of the original test, and only one retake is allowed per full test. It is available for both Academic and General Training, and you receive a new Test Report Form combining the retaken skill with your three original scores (IELTS).
When should you use it? When three skills are at your target and one sits below it. When should you resit everything? When the gap spans more than one skill. There is no compulsory waiting period between tests — IELTS says you can apply to resit as soon as you feel ready (IELTS) — and readiness, not the calendar, is the real test.
Remember that organisations are recommended to treat results as valid for two years, though some accept them for longer (IELTS). Count from your course start date, not from your application date.
Where to practise: official resources first
IELTS publishes free sample test questions and videos explaining how Writing is scored, alongside apps, webinars and books from its partners (IELTS). Start there before anything else, because only official material reflects the real question formats and marking. We have also shared apps for building listening and speaking at home (KD International, 2 October 2019) — and the principle still holds: short daily practice beats one intensive day a week.
KD International’s published services include English language programs, with partnerships including LSI language institute (a discount for KD students) and ILSC. We help you choose a language program that matches your target score and your preparation window.
Six steps to raise your band
- Write down the score your program requires, and any per-skill minimum it sets.
- Sit a full timed practice test from the official sample questions and record your result in all four skills.
- Turn the gap into numbers: how many correct answers you are short in Listening and Reading, and which criterion is holding down your Writing and Speaking.
- Spend most of your time on the two weakest skills, because the averaging formula rewards lifting them.
- Repeat the timed practice test periodically, and do not book the real test until you hit your target in practice.
- If one skill still falls short after the test, weigh a single-skill retake within 60 days against resitting the whole test.
The takeaway
Start from the score your program requires, then break it into numbers: how many correct answers in Listening and Reading, and which criterion is holding your Writing down. Work on the weakest skill, practise under full timing, and consider a single-skill retake when only one skill is short.

Frequently asked questions
It is the average of your four section bands, rounded to the nearest half band. An average ending in.25 rounds up to the next half band and.75 rounds up to the next whole band. The official example: 6.5, 6.5, 5.0 and 7.0 average 6.25, which becomes 6.5.
About 30 correct out of 40 in Listening, about 30 in Academic Reading, and about 35 in General Training Reading. These are the average marks published by IELTS and vary slightly between test versions.
Academic is for people planning to study in an English-speaking country and measures readiness for university-level work. General Training suits migration or below-degree study. Listening and Speaking are identical; Reading and Writing differ.
It lets you retake a single section instead of the whole test, provided your original test was IELTS on computer at a participating centre, and you book and sit the retake within 60 days of the original test, once per full test. You receive a new Test Report Form.
There is no compulsory waiting period; IELTS says you can apply to resit as soon as you feel ready. The practical test is whether you have changed how you prepare and are hitting your target score in timed practice.
IELTS recommends that results be treated as valid for two years from the test date, and organisations may choose to accept them for longer. Measure that window against your course start date, not your application date.
Each university and program sets its own score, and health and education programs often require more than the university’s general minimum. ANU, for example, accepts IELTS, TOEFL iBT, Cambridge C1 Advanced and PTE Academic and refers applicants to its policy and program requirements for the score.
