Are the IELTS Advantage reading and listening practice tests the same as official materials?
No, they are not. The IELTS Advantage practice tests are provided specifically so that you can practise the strategies given on the course. However, as indicated on the tests, the scores you get for them and the level of difficulty are not indicative of how you will perform with official materials, so once you have mastered the strategies, you should switch to official Cambridge materials only.
