Should I stop using AI if scores feel wrong?

No, recalibrate with blind tasks and criterion logs; abandon headline bands, not the tool.

When am I ready to book IELTS?

Trust but Verify: AI IELTS Strategy

Direct answer

Trust but verify means using AI for high-volume criterion feedback while proving readiness on blind prompts and periodic human checks, not believing headline bands on familiar tasks. Trust AI for error patterns, timed drills, and rubric vocabulary. Verify with unseen Writing Task 2 prompts, unscripted Speaking recordings, and a personal calibration offset. Book IELTS only when verified performance, not AI praise, matches your target within 0.5 band.

What to trust AI for

Grammar drills Error tagging and pattern frequency between sessions

Timed practice Volume of essays and Speaking clips under clock pressure

Criterion vocabulary Learning descriptor language for self-audit

What to verify independently

Claim	Verify with…
AI Band 7 Writing	Blind Task 2 + human TR check
AI Band 7 Speaking	Unseen Part 2 audio + mock FC score
Reading/Listening AI score	Timed paper test, see when Reading AI is meaningless

Weekly trust-but-verify loop

Mon–Thu: AI drills on known weak criterion (one leak only).
Friday: blind productive task, no outline, no template.
Score blind task with AI + log criterion gaps.
Biweekly: human or certified mock on same blind submission.
Adjust study plan from lowest verified criterion, not mood.

Build offsets via calibration framework.

Key takeaways: Trust but Verify

Trust AI for drill volume and error typing, not exam readiness alone.
Verify on blind prompts; familiarity inflates every tool.
Log criterion gaps; ignore averaged headline bands.
Book when verified mocks align, not when AI praise feels good.
