After your purchase, your tasks will be added to your dashboard. You do not need to answer them all today. When you're ready, you can read your questions and answer them in the time you are given. The time limits are set so that you can practice answering under real test-taking conditions. Once submitted, your answers will be read by qualified IELTS tutors. Your tutor will provide you with a score and feedback. Not sure about your feedback? Don't worry! You can ask follow-up questions to be sure that you know what you need to work on to improve your score for the next time.
Full test packs show you exactly what you'll do on test day. You'll get one of each task type and are given the option to do it timed exactly as it is when you take the IELTS. This is great for all-round preparation.
