You finish a Task 2 essay at 9 p.m. on a Tuesday. You upload it somewhere — a teacher, a service, an app — and now you wait. How long should you actually wait before you write another draft? Different services give very different answers, and the answer tells you a lot about whether you’re getting feedback that will move your band.
Why turnaround matters more than people think
An essay marked four days later is graded against a draft you no longer remember writing. The leak the marker flags (“you missed the second part of the prompt”) lands after you’ve mentally moved on; you nod, you note it, you don’t apply it. The next essay carries the same leak.
Compare to feedback that lands inside 48 hours: you can still see why you wrote what you wrote. The fix is fresh. You re-attempt the same prompt or a near-identical one within the week, and the markers from your last submission still echo. That’s how bands move — tight feedback loops, not big-bang monthly reviews.
The four turnaround categories
1. Instant AI feedback (~30 seconds)
Several services now grade Task 2 essays automatically against the band descriptors and return a per-criterion score plus a paragraph of notes. Useful for a sanity check after a draft. Useless on its own — the AI is unfailingly polite, can’t see when you’ve misread the prompt, and gives advice that applies to the average Band-6 student rather than to you specifically.
Use it as a pre-check. Don’t use it as a substitute for human review.
2. Same-day human review (4–12 hours)
Rare. Usually a teacher who happens to be online when you submit, or a service that surge-prices for express turnaround. The quality bar is the question: a same-day review that’s actually four lines of generic advice is worse than a 48-hour review with margin notes. Ask what the deliverable looks like before you pay extra for speed.
3. The 48-hour SLA (the sweet spot)
Far enough out that the human grading it has time to actually read the essay properly. Close enough that you can incorporate the fix into your next draft within the same week. This is the target you should be looking for from any service that bills itself as “1:1 IELTS coaching”.
The catch: most teachers say 48 hours and miss it regularly because they don’t track turnaround as a hard operational metric. A service with a real queue and a timer hits the SLA; a service that promises 48 hours from a Gmail inbox usually doesn’t.
4. The 5–10 day shrug
The default for many solo teachers, especially during exam seasons (March, August, late November) when their inbox piles up. You submit, you wait, you nudge, you get a reply two days after the nudge. The bands you see are accurate but the feedback loop is broken — you’re writing two drafts a week while the marker is a draft and a half behind.
If you’re paying for IELTS prep and turnaround is open-ended, the rate is too high regardless of the headline price.

What our 48-hour SLA actually means
On the platform side: every submission lands in a grading queue with a timer. Submissions older than 48 hours get flagged automatically — visible to Isabel, visible to a student asking why a review is late. The SLA is a queue rule, not a promise.
On the deliverable side: every writing submission comes back as a per-criterion report (Task Response, Coherence & Cohesion, Lexical Resource, Grammatical Range & Accuracy), with margin notes on the actual sentences and a one-line next step. Same format whether you bought a $29 single grading or you’re inside the $399 program.
Speaking practice turnaround
Speaking is harder for most services to turn around quickly because audio takes longer to review than text. The honest tradeoff: for genuine per-criterion speaking feedback (Fluency & Coherence, Lexical Resource, Grammatical Range & Accuracy, Pronunciation) the same 48-hour window applies. AI speech-grading is improving but still misses register, hedging patterns, and pronunciation-specific issues that an examiner would mark.
We grade speaking off audio you record in your browser, not off a single voice memo over WhatsApp. Same 48-hour SLA as writing.
Mock exam turnaround
A full IELTS mock is reading + writing + listening + speaking, which is a lot of grading. The realistic turnaround for a real per-criterion mock-exam grading is 48–72 hours — ours lands inside 48 hours for the full four-skill exam. Auto-graded reading and listening return instantly; writing and speaking are where the human review window applies.
Three questions to ask any IELTS prep service
- What’s the SLA on writing feedback? If they can’t answer in a number of hours, they don’t have one.
- Can I see a sample of the feedback before I pay?Some services show you a redacted real example. Most can’t, because the deliverable isn’t standardised. That’s a tell.
- What happens to a submission that goes over the SLA?Real answer: it gets flagged, you get a heads-up, the timer keeps running. Bad answer: silence until you nudge.
The headline price of an IELTS prep service tells you almost nothing. The SLA on feedback — in hours, with consequences — tells you almost everything.
