Sources & methodology
Our practice is written to match the real IELTS. We follow the official test format for all four sections and the 0–9 band scale, write our own tasks and feedback against them, and mirror the Academic and General Training formats. Here’s exactly what we align to — and a clear note on our independence.

These are the official IELTS sources that define the test. We reference them so our practice reflects the real exam.

The official 0–9 band scale, how the four sections combine into an overall band, and what each band means. The band references on our pages trace here.
The official specification of the Listening, Reading, Writing, and Speaking sections and the Academic vs General Training difference our practice mirrors.

Official test information and booking from IDP, an IELTS co-owner — the authority for current dates, fees, and rules in many regions.
How the content is made
Our editorial team — Koydo Lyceum — writes original practice tasks and feedback mapped to the official Listening, Reading, Writing, and Speaking formats and the band descriptors, then reviews them for accuracy. We mirror the real Academic and General Training formats so practice feels like the actual test.
