About CD IELTS Prep
An online practice platform built for one thing: the computer-delivered IELTS test.
What we do
CD IELTS Prep is practice software for the computer-delivered IELTS test. Everything on the platform — the exam screens, the timers, the question types, the highlighting and notes tools — is built to match what you will see on test day, so the interface holds no surprises when it matters.
You practise, we mark. Listening and Reading are scored instantly against answer keys, Writing gets structured algorithmic feedback, and Speaking sets let you record and review your own answers. New material is added every week.
What you can practise
Full mock tests
Complete Listening, Reading and Writing mocks in the same on-screen format as the real computer-delivered test, with the same timing and question types.
60+ practice days
A large library of Listening and Reading practice days, so you can drill one skill at a time instead of always sitting a full test.
Instant rule-based marking
Listening and Reading answers are marked the moment you finish, using published answer keys and transparent matching rules you can audit question by question.
Writing feedback
Algorithmic feedback on both writing tasks — task response, structure, vocabulary and grammar signals — plus band 9 sample answers to compare against.
Speaking practice
Timed speaking sets with cue cards and in-browser recording, so you can hear yourself back and track how your answers develop.
New material weekly
Fresh predicted and recent-exam-style material is added every week, so practice stays close to what candidates are seeing right now.
Our approach
Honest, auditable scoring
Every mark can be traced: you can see the answer key, the matching rule that accepted or rejected your answer, and the band conversion table used. No black boxes, and no inflated scores to make the product feel good.
Estimates, not official results
Band scores on this platform are practice estimates produced by our own assessment engine. They are designed to be a realistic guide to where you stand — they are not official IELTS results and cannot be used as one.
Independence
CD IELTS Prep is an independent practice platform. We are not affiliated with, endorsed by, or connected to IELTS, the British Council, IDP Education, or Cambridge University Press & Assessment. IELTS is a registered trademark of those organisations. To book the official test, go through an official test centre.
