The IELTS Listening module is all about your understanding of a variety of accents: British, American, and New Zealand. If you are unable to comprehend what natives speak, you primarily need to focus more on their speech.

In order to brush up your listening skills, you ought to listen to as much content as you can in English. To illustrate further, watch English movies with captions on, listen to podcasts and try to imitate the native speakers. This way, not only your fluency will improve but also your confidence will boost.

I receive several comments on YouTube, where learners ask me whether they should practice listening at 1X, 1.25X, or 1.5X speed, and my answer always is 1X is the ideal speed; however, once a week, they can practice at 1.25X. Also, learners should consider going through the audio scripts available in all Cambridge books, just after the completion of each listening test. This way, they will know how to rectify their mistakes and also, get to know the exact words the speaker used or the words they missed. This habit of analyzing the mistakes at the end will gradually help in improving your listening scores. Besides this, the more you listen, the better your listening and speaking skills be.

At last, in the IELTS exam, all the modules are co-related to each other. By reading more, your writing can get better, and similar is the case for listening and speaking modules. So, simply listen and read more, and the battle of this exam will be won.
