Free IELTS practice tests
British Council has plenty of free IELTS practice tests available online. You can take them as many times as you need to build your confidence, practice your English and get used to the test format, so you feel ready for the real exam.
The IELTS online practice tests include both the questions and the answers so that you can take the test as you would on the day, then mark how well you did afterwards. Recreate the exam conditions with time restrictions allocated to each section (Reading, Writing, Speaking and Listening), so that you are more prepared for the exam conditions on the day.
