Answer key
Cambridge IELTS Answers — Every Published Key
The published key for every Listening and Reading paper, free and with no account.
The answer keys for all 168 Cambridge IELTS Listening and Reading papers are on this site, one page per paper, free and with nothing to sign up for. They come from the same files this site marks candidates against, so the key you read here and the mark the platform gives cannot disagree. Pick a book below.
Writing and Speaking are not here, and that is not an omission: neither is marked against a list of answers. They are scored against the four published band descriptors — task response, coherence, lexical resource and grammar — by an examiner or by our AI, which is why no honest site can publish a key for them. For Listening and Reading, remember that a raw score out of 40 only has four published conversion points; anything claiming to turn 27 into an exact band invented the number.
