Here is a list of strategies that you can use for each listening question type:

Two other important tips are:
1. Be aware of connected speech i.e. when a native English speaker is speaking they often join the sounds of words together, so you may think you have heard one word but actually you have heard three or four. Of course we write words separately such as, 'how are you', but actually we say 'howau'. This can make a big difference to a students comprehension of English.
2. Practice like the exam. In the test you will only hear the recording once, so it is a good idea to get used to this during practice sessions. And also practice listening for long periods of time. The test is over 30 minutes which is a long time to listen to a foreign language if you are not used to it! Good luck!
