How to go from Band 6 to Band 7.
The most requested move in IELTS, and the most misunderstood: it is won on error density and development, not on longer words.
The short version. Band 6 says your English works despite its errors. Band 7 says stretches of it work without errors: frequent error-free sentences, one idea properly developed rather than three ideas listed, and enough flexibility that you are choosing structures rather than surviving them. Reading and Listening are arithmetic; Writing and Speaking are where the half band usually hides.
What separates 6 from 7 on the real criteria.
The descriptors change their verbs at this boundary. Read them closely and the plan writes itself.
At Band 6 the criteria tolerate: some errors that rarely block communication, ideas that are relevant but thinly developed, cohesion that is visible but mechanical. At Band 7 the tolerances tighten in a specific way: grammar must produce frequent error-free sentences, ideas must be extended and supported, paragraphing must carry one central topic each, and vocabulary must show flexibility and precision, with occasional less common items used correctly rather than decoratively.
Notice what is absent: nothing at 7 demands rare words or exotic structures. The boundary rewards control. A candidate who writes plainly and accurately outperforms one who attempts complexity and litters it with slips. If you remember one sentence from this page, make it that one.

Where the half band usually lives.
Most 6.0 and 6.5 writers lose the band in the same two places: development and error density.
Task Response. A Band 6 essay tends to list: three reasons, one sentence each. A Band 7 essay develops: one reason, then the example, then the consequence, then the qualification. Take a question from the essay question bank and practise writing a body paragraph that spends its whole length on a single idea.
Grammatical accuracy. Count your error-free sentences honestly. If fewer than half your sentences survive without a slip, the grammar criterion holds the band at 6 no matter how ambitious the structures are. Run a draft through the AI writing checker for an indicative read, or study a full marked report to see how a tutor annotates the gap. The marking archive shows the same corrections across dozens of scripts.
Then drill under timed conditions with the Academic writing papers, or the GT letter guide if you sit General Training.
Flexibility, not vocabulary.
At 6 you answer the question. At 7 you develop the answer without being pushed.
The Speaking descriptors reward the candidate who speaks at length without losing coherence, paraphrases when a word is missing rather than stopping, and uses complex structures with enough control that the errors do not distract. The fastest way to hear the difference is a side-by-side: the same answers at Band 6 and Band 8, with what lifts them made explicit.
Then work the parts: Part 1 topics with paired models, Part 2 cue cards, and Part 3 discussion questions, where the 6-to-7 jump is most visible, because Part 3 is where developed answers are demanded rather than merely welcomed.
Arithmetic, not judgement.
These two skills have no examiner. The band is a raw-score conversion, so the plan is volume plus an error audit.
Band 6 to Band 7 in Academic Reading is roughly the difference between 23 and 30 correct answers out of 40; in Listening, roughly 23 and 30 as well. The exact conversion shifts slightly between test versions, so treat those as orientation, and use the band score calculator to translate any practice score.
The move is made by auditing which question types cost you marks, then drilling those. Sit the Reading passages and the Listening practice tests under time, mark them, and keep a list of the question types you miss. Seven wrong answers is one weak question type, not a language ceiling.
Study what pays at 7. Ignore what doesn't.
The syllabus for this half band is short: a handful of structures used accurately, and precision over rarity.
The structures that earn their keep at Band 7 are catalogued on grammar by band: conditionals, relative clauses, passives where they belong, and linking that is grammatical rather than bolted on. Drill each until it is boring; the grammar game keeps score. For vocabulary, the word upgrader shows the precise-for-vague swaps that read as flexibility, and lexical resource explains what the criterion actually measures.
Diagnose first. Then drill the two weakest criteria.
A shape, not a promise: how fast the gap closes depends on where you start and how much you practise.
Week 1, diagnose. One timed Reading test, one timed Listening test, one essay through the checker, one Part 2 answer recorded and compared against the 6 vs 8 models. Convert the receptive scores with the calculator. You now know which two criteria are cheapest to fix.
Weeks 2 and 3, drill the two weakest. Not everything at once: the two criteria the diagnosis named, worked daily in short sessions, with every error explained before it is corrected. A correction you cannot explain is one you will make again.
Week 4, retest. The same instruments as week 1, timed. Whatever has not moved is what a teacher is for. And once 7 is yours, the next half band is a different climb.
The hard part isn't the scale. It's seeing your own band honestly.
Most people sit half a band below where they think they are, and can't tell why.
The first lesson is a full assessment: I'll assess your current level against these criteria and tell you, plainly, what's holding the band down and what to do about it. Lessons are £20 for fifty minutes, one to one, in proper British English. Or start free, sit a Reading test or study the Band 7 structures.
