The honest answer is: usually several months of consistent, focused work — and the exact number depends far more on which skills need to move than on total study hours.
Anyone promising “7.5 in two weeks” is selling something. But the opposite myth — that band scores only move with years of immersion — is also wrong. A 1.5-band jump is a realistic goal with a plan. Here is how to build one.
Why 6.0 to 7.5 is not one problem
Your overall band is the average of four skills, rounded to the nearest half band. That has a practical consequence: a candidate at overall 6.0 is rarely at 6.0 in everything. A typical profile looks like Listening 6.5, Reading 6.5, Writing 5.5, Speaking 6.0.
That profile changes the question entirely. Reaching overall 7.5 does not mean “improve everything by 1.5”. It means Writing needs to move two full bands while Listening needs one. The plan for those two problems is completely different — and this is why generic study schedules fail.
Start by finding your real profile. Take a full mock test under timed conditions and get a band for each skill separately. Everything below follows from those four numbers.
What each kind of gap takes
Receptive skills move faster. Listening and Reading improve with volume plus deliberate review, because the gap is usually specific: certain question types, speed on long passages, or accents you have not trained on. A half-band to full-band improvement in a receptive skill over one to two months of near-daily practice is a common experience.
Writing moves slowest — and moves almost never without feedback. Writing thirty essays without feedback mostly practises your existing mistakes. The band moves when you learn which criterion is capping you — Task Response, Coherence, Lexical Resource, or Grammar — and drill that specifically. A two-band writing gap is realistically a three-to-six-month project of write → get criterion-level feedback → rewrite. This is exactly the loop IELTS Studio’s writing practice is built around; how the criteria actually work is covered in how the writing band scale works.
Speaking sits in the middle. Fluency responds to sheer speaking time; pronunciation and grammatical range respond to targeted correction. Recording yourself answering real Part 2 cue cards and reviewing the feedback beats silent preparation every time.
A realistic structure for the months
Rather than promising a universal number of weeks, here is the structure that consistent improvers follow:
Phase 1 — diagnosis (week 1). Full mock, four skill bands, one identified weakest skill. Set a target profile: to reach overall 7.5 you need your four bands to average 7.25 or above, so work out the combination you will actually aim for.
Phase 2 — asymmetric work (the bulk of the time). Spend roughly half your study time on your weakest skill and split the rest across the others. Practise daily if possible; five 40-minute sessions beat one five-hour Saturday. Every practice session ends with review — the review is the study; the test was just the setup.
Phase 3 — re-test and adjust (every 3–4 weeks). Another full mock. Compare the profile, not just the overall number. If Writing moved from 5.5 to 6.0, the plan is working; keep going. If a skill has stalled for two consecutive mocks, the problem is usually method, not effort — change how you review before adding hours.
Phase 4 — exam conditioning (final 2–3 weeks). Full tests under strict timing, no pausing, exam-day schedule. By now you are not learning English; you are rehearsing performance.
The two things that actually predict the timeline
Across all the variation, two factors dominate how long this takes:
- Feedback quality. Candidates who know their per-criterion scores fix the right things. Candidates who only know “6.0” fix random things.
- Consistency. The candidates who reach 7.5 are almost never the ones who studied the most in any single week. They are the ones who never had a zero week.
Track both. If you can see your band trend per skill across weeks — the way the progress dashboard in IELTS Studio shows it — you will also get the motivational side effect: watching a criterion score move is what keeps the streak alive in month three.
