Fifty dollars buys you exactly one officially marked practice essay or five months of unlimited AI-checked ones. Which is the better spend for your band? The honest answer is “both, at different moments”, and this guide shows exactly when each earns its money.
Quick answer: they answer different questions. IELTS Progress Check (~$50, marked by official IELTS markers, results in days) tells you where you are with real credibility — use it once, shortly before the exam. AI checkers (~$10/month, instant) tell you what to fix after every essay — use them for the daily practice loop. The candidates who improve fastest use AI for volume and the official check for calibration.
IELTS Progress Check is the official practice test run by the IELTS partners (British Council, IDP and Cambridge): the real format, marked by trained IELTS markers, an indicative band score with marker feedback, results within about five days. That officialness is the whole value — no AI estimate matches its credibility, because the people scoring it are the people who score the real thing.
The honest flip side: you pay per attempt (~$50), wait days, and the feedback is brief — it tells you where you are far better than it tells you how to improve. As a practice loop, one essay per $50 per several days simply doesn’t iterate.
Instant scoring against the same four criteria: Task Achievement, Coherence, Lexical Resource, Grammar — with sentence-level feedback, and the math is blunt: one official attempt (~$50) costs as much as five months of unlimited AI checks. Accuracy is the trade-off: ±0.5 band for well-calibrated tools, so treat scores as ranges.

Prices as of September 2026 — check current pages.
- Weeks 1–4: AI volume. Two-three checked essays weekly; watch per-criterion trends, drill the weakest one. Cost: one subscription.
- When AI scores plateau at target: book IELTS Progress Check as the official confirmation. One attempt, 2–4 weeks before the real exam.
- If the official band lands 0.5+ below your AI trend: recalibrate — your Task Achievement is usually the culprit (AI is most generous there). Two more weeks of targeted essays, then the real exam.
- Skip the official check only if your target is modest (6.0–6.5) and your AI trend sits comfortably above it.

Is IELTS Progress Check worth it?
Yes — once, as a benchmark. It is the only practice test marked by official IELTS markers, so its score carries real weight. At ~$50 per attempt with results in days, it is too slow and expensive to be your practice loop.
How accurate are AI checkers compared to official marking?
Well-calibrated AI tools score within about ±0.5 band of human examiners for most essays — accurate enough to track progress and find weak criteria, not a substitute for the official number.
When should I take IELTS Progress Check?
Two to four weeks before your real exam, after your AI-tracked scores have plateaued at your target. Taking it too early wastes the benchmark on a band you already know needs work.
Can I prepare using only IELTS Progress Check?
Practically no — at ~$50 per test and days per result, iterating on feedback would cost hundreds and take months. The efficient loop is AI for daily volume, official check for final calibration.
Does the real IELTS use AI marking?
The official IELTS Writing test is marked by trained human examiners. AI tools are preparation aids — they recreate the marking criteria so you can practice against them.
