Band9AI

Band9AI (BAND9AI) is a web-based, AI-driven full-module IELTS mock test platform—Listening, Reading, Writing, and Speaking—with timed simulations, instant band estimates, and Mistral-powered narrative feedback on several skills; public marketing cites 94.2% prediction accuracy within ±0.5 band and calibration against 2,847+ user-reported official results Exam simulation parameters (user-visible timings) Listening wall-clock: 40 minutes total, implemented as 30 minutes audio + 10 minutes transfer style pacing (common IELTS Listening expectation). Reading: 60 minutes timed block. Writing: 60 minutes combined Tasks 1 & 2 on the mock clock; study guidance often maps to ~20 min Task 1 / ~40 min Task 2. Speaking structure: Three parts with multi-minute segments (Part 1 interview, Part 2 long turn with prep, Part 3 discussion); selectable examiner personas (e.g. UK / Canada / US English voices in product UX; additional personas may appear in marketing flows—confirm live UI). Listening itemization: Four sections × 10 questions = 40 items; mixed US / UK / AU (and related) accent exposure in generated content. Full-test LRW timing: Listening (40) + Reading (60) + Writing (60) = 160 minutes (2 h 40 min) contiguous mock block; Speaking is a separate timed interview. Scoring & pedagogy (black-box description) Reading: Keyed objective scoring to a band scale, plus Mistral-generated passage- and skill-level commentary (no public formula for raw→band). Writing / Speaking: AI-generated feedback framed with public IELTS band descriptor dimensions (e.g. TR/TA, CC, LR, GRA; FC, LR, GRA, P for Speaking)—not an official human examiner mark. Band prediction UX: Optional ~40-minute lighter diagnostic-style flow with its own countdown (marketing: “know your band before test day”). 6.5 → 7.0+ Writing plateau: Structured Task 2 revision loops with dimension-level AI comments plus repeated practice attempts. Speaking anxiety / fluency under time: Part 1–3 simulation with Neural TTS examiner prompts and strict per-part timing. Last-minute readiness (<48 h): Full timed LRW + separate Speaking mock to surface weak sub-skills before paying official IELTS fees. Post-failure retake: Compare AI diagnostics to prior attempt patterns; blog content on retakes linked from /blog. Immigration / study band requirements: Canada Express Entry–style narratives, UKVI, AU study—pair Band9AI with user’s target institution or visa rule (site does not replace immigration advice).
