How Long to Prepare for IELTS? An Honest Answer by Level

The honest answer by starting level

IELTS bands map approximately onto the CEFR levels, which gives a realistic way to estimate the gap. The table assumes eight to ten focused hours a week and a diagnostic mock at the start.

The table also explains why candidates who "studied for a year" sometimes score the same as candidates who studied for two months. The year was spent at B1 building general English, which was necessary, and the two months were spent at B2 on test technique, which is what IELTS actually measures. Both parts are real work; they are just different kinds of work and they take different amounts of time.

Two caveats. First, these are ranges for someone whose four skills are at a similar level. A candidate with band 7 Reading and band 5.5 Writing needs the Writing timeline, not the average. Second, moving from 6.5 to 7.5 takes far longer than moving from 5.5 to 6.5, because the descriptors at 7 and above reward control and precision, which only come from corrected repetition.

Hours per week that move the needle

The number that matters is not total hours but hours of practice that produce feedback. Reading an article is input; answering forty questions on it under time and logging which types you missed is practice. Watching a video about Task 2 is input; writing a timed essay and reading a four-criterion correction is practice. For most candidates, eight to ten hours a week of this kind of work is sustainable alongside a job or study and produces visible movement within a month. Twenty hours a week of unfocused input produces fatigue and the same score.

Skill-by-skill time split

Split the hours according to the diagnostic, not evenly. Most candidates do the opposite: they spend the hours on the skill they enjoy, usually Reading or Listening, and leave Writing until the week before the test. A typical B2 candidate at 6.0 overall has Reading and Listening close to 6.5 and Writing at 5.5. Their week should look like: four hours Writing (two timed essays with correction and a rewrite), two hours Speaking (daily ten-minute recorded answers), one hour Reading (one timed passage set and an error log) and one hour Listening. Reverse the weighting if the diagnostic shows the opposite pattern. Re-run the diagnostic every four weeks and re-split. A skill that reaches the target can drop to maintenance: one timed paper a fortnight is enough to keep Reading at 7.

Signs you are ready

• Two consecutive full mocks, taken a week apart under exam timing, at or above the target band in every skill.
• Your Writing corrections show the same two or three error types, and you now catch most of them in the final check.
• You finish Reading with five minutes to spare and Listening without leaving questions blank.
• In Speaking, your pauses are about ideas, not words; you no longer self-correct every sentence.
• The band estimate has not changed in two weeks. Further study gives diminishing returns; it is time to book.

If only one of these is missing, it is usually the first. Candidates who score the target once and book immediately often sit the real test on a bad day and come up half a band short. Two mocks a week apart cost a few hours and remove most of that risk; a second test sitting costs the full fee and another month.

Study plans for 4, 8 and 12 weeks

Four weeks (C1, or B2 aiming for 6.5): week 1 diagnostic and test format; weeks 2–3 the weakest skill, four hours a week, plus timed Reading and Listening papers; week 4 two full mocks and review. This plan teaches technique, not language.

Eight weeks (B2 aiming for 7): weeks 1–3 Writing: two corrected essays per week, grammar error log, Task 1 overviews. Weeks 4–5 Speaking: daily recorded Part 2 and Part 3 answers scored on the four criteria. Weeks 6–7 Reading and Listening: one full paper each per week, question-type log. Week 8 two full mocks.

Twelve weeks (B2 aiming for 7.5, or strong B1 aiming for 6.5): the eight-week plan preceded by four weeks of language building inside the five IELTS topic areas: collocations, complex sentence patterns and paraphrase, each practised in writing and speech. The gap between band 6 and band 7 in each skill is spelled out in our guide to what changes from IELTS band 6 to 7.

Practise with Langujet

The plan starts with a number, not a guess. Take an IELTS mock test to get a band estimate in all four skills, then use the Langujet IELTS hub to find the practice for the skill that is furthest from your target. Repeat the mock every four weeks; when two in a row hit the target, book the real test.
