You can take the IELTS Academic at a test centre or remotely online. The test time is 2 hours and 45 minutes, and the format is the same wherever it is taken.
Choose the IELTS Academic test if you wish to study at undergraduate or postgraduate levels, or if you are seeking professional registration, e.g. doctors and nurses.
In IELTS, there are four papers: Listening, Reading, Writing and Speaking. The Speaking and Listening tests are the same in both the Academic and the General Training tests, but the Reading and Writing tests are different.
