Writing task 1 practice questions (academic test)
Real IELTS questions
(This is the official page of IDP Education, which owns the IELTS test along with the British Council and Cambridge Assessment English, so the questions are reliable.)
(One practice question provided by the British Council.)
(These Cambridge IELTS books are THE BEST place to get real IELTS practice questions [including for the listening, reading and speaking tests]. At the back of each book you can also find model answers and examiners’ comments.)
Unofficial practice questions
The unofficial practice questions are often invented or provided by test-takers from memory. As a result, they frequently contain errors and may be slightly different from the real questions given in the test. This can cause significant problems when practising.
I strongly recommend that you only use real IELTS questions when you practise. Start with the sources at the top of this page and then use the official Cambridge IELTS books.
After that, if you still need more practice questions, you can find some on the unofficial pages above.
