New to IELTS? Begin right here. In a few minutes you'll know exactly what the test measures, how it is scored, how this app is organised — and where you stand today.
IELTS Academic has four skills. Listening, Reading and Writing are taken back-to-back on the same day; Speaking may be on the same day or a few days apart.
| Skill | Format | Timing |
|---|---|---|
| Listening | 4 sections, 40 questions — recordings played once only | ~30 min |
| Reading | 3 passages, 40 questions, 11 official task types | 60 min |
| Writing | Task 1 (describe visual data, 150+ words) + Task 2 (essay, 250+ words) | 60 min (20 + 40) |
| Speaking | 3 parts — interview, long turn, discussion | 11–14 min |
Every skill is scored on the same 0–9 band scale in half-band steps (5.5, 6.0, 6.5…). Your Overall Band is the average of your four skill bands, rounded. Listening and Reading come from a fixed raw-score conversion; Writing and Speaking are judged by trained examiners — which is exactly why technique and practice matter most there.
Every lesson here comes from CILL's IELTS classroom book, and keeps the book's own chapter numbers so the app and the book always match. The chapters are grouped into three blocks:
This is Chapter 1. The skill modules then follow the book: Reading = Chapters 2–6, Writing = 7–14, Listening = 15–18, and Speaking = 19–21. So when a module opens at Chapter 2, nothing is missing — Chapter 1 is this orientation you are reading now.

IELTS loves to say the same thing in different words. This tool trains you to notice it — every single time.
No random dictionary lists. Every word is explained the way IELTS actually uses it, in the right register.
Saved words turn into a short quiz — you pick the sentence with the same meaning. Real exam practice, not memorising.
IELTS often rewrites a whole sentence, not a single word. We train you to catch that shift too.
