You can choose to take IELTS on a computer for both the General Training and Academic tests. The test format, question types, time allocated to each test part and content is the same for both IELTS on computer test and the IELTS on paper test. The only difference is in your test day experience. If you choose to complete your IELTS test on computer, you will do the Reading, Listening, and Writing parts of the test using a computer. All answers will be typed on the screen. You will also be able to write notes on a notes sheet during the Listening test.
The IELTS Speaking remains the same, with a face-to-face interview with an examiner. The Speaking test will be completed either just before, or just after the Reading, Listening, and Writing test parts.
Taking IELTS on a computer has many benefits. For example, your results arrive a lot faster. With IELTS on computer your results will be available within 3 to 5 business days.
IELTS Academic and General Training are two wholly separate types of test, for two different purposes. While some individual organisations may accept an Academic result in the place of a General Training one, this decision is up to them. You will need to contact your specific organisation to learn more.
