IELTS24 vs BAND9AI: Mock Platform vs Criterion AI Scoring
Platform comparison · May 2026
IELTS24-style platforms prioritise full mock tests, question banks, and exam-format familiarity. BAND9AI prioritises criterion-level scoring on your own Writing and Speaking under timed conditions. They solve different bottlenecks: more mocks help Listening/Reading rhythm and stamina; rubric diagnosis helps when you keep scoring 6–6.5 on production skills despite high mock volume. Use IELTS24 (or similar) for volume—use BAND9AI when you need to know which descriptor leaks before rebooking.
