Top 5 IELTS Listening Tips
Familiarise yourself with a range of accents.
The IELTS Listening test will feature a range of accents to reflect the international nature of English. Therefore, you should get used to listening to accents from a range of English-speaking countries.
Instead of just listening to the BBC, you could try smaller regional radio stations or actively watching TV shows from different English-speaking countries. A quick search on Google is all you need to find these.Don’t lose your concentration.
It can be difficult to stay focused during your IELTS Listening test, but it’s also extremely important if you want to score a Band 7 or above.
To improve your concentration you need to practice active listening.
This involves setting yourself small tasks when you are practising and actually doing something when you are listening, just like you will be in your test.Follow the instructions carefully.
This especially applies when it comes to the word limit. If the question states ‘No more than three words’ then you can’t write any more than this. If your answer is four words it will be incorrect.Familiarise yourself with the different question types.
Doing so will mean you’ll know exactly what to expect on test day and how to react to the question types you’re given. To help you with this, you should use genuine practice IELTS past papers.Practice listening to things only once.
Lots of teachers allow their students to listen to a recording 3 or 4 times. However, I would strongly recommend practising the exam under exam conditions and that means listening just once.
