IDP IELTS Practice vs BAND9AI
Platform comparison · May 2026
Direct answer
IDP IELTS Practice is an official-style hub for familiar test formats and volume; BAND9AI is criterion-level AI scoring on your timed essays and Speaking. They solve different problems: IDP builds exposure to real item types; BAND9AI diagnoses which band descriptor leaks on your output. Many students need both—official practice for format, rubric AI for honest calibration before booking.
Two different product models
IDP IELTS Practice optimizes curriculum completion. BAND9AI optimizes rubric diagnosis on submitted work. Neither replaces the other if your gap is undiagnosed Task Response or false Speaking confidence.
IDP IELTS Practice strength Structured lessons, pacing, familiar test formats
