Everyone wants a number. The honest answer is a range that depends on which criterion is limiting you — so here is the reasoning, and the four profiles that cover most students.
A band score is a sample of your speaking on one day, judged by a trained examiner against four criteria. Lessons change your underlying ability; the test measures one performance. Between those two things sit nerves, the questions you happen to get, and how you slept.
Anyone quoting "10 lessons = half a band" is quoting a marketing number. What a good tutor can do is look at your speaking, name the limiting criterion, and give you an honest range with the reasoning attached.
Your English is fine. Your Part 2 answers have no shape, your Part 3 answers are one sentence long, and you have never been taught what the examiner is scoring. This is the fastest profile to move: typically 6–10 lessons, with homework that involves recording yourself.
You speak fluently and confidently and make the same four grammatical errors constantly — articles, verb tense consistency, subject-verb agreement. Fixing a fossilised error takes repetition over weeks, not explanation. Typically 15–25 lessons.
Listeners have to work. Usually it is word stress and consonant clusters rather than individual sounds. Pronunciation responds well to short daily practice, poorly to weekly-only lessons, so the calendar matters more than the count. Typically 10–16 lessons spread over 8+ weeks.
This is a general proficiency gap, not a test-technique gap. It is a six-to-twelve-month project and no package will shortcut it. A good tutor will say so, and will tell you to test later rather than take the exam three times.
Take the free 25-minute diagnostic. Ask the tutor: which criterion is capping me, which profile am I, and what range would you put on it? You will get a specific answer, and if you do not, that is your answer about the tutor.

They are not interchangeable, and the choice is usually made for you by an institution — not by which test feels easier. A practical decision guide.
