Even an average user of English can score maximum in the listening module of IELTS. All you have to do is know about the pattern and take a good number of practice tests.
The most important thing that one has to remember regarding listening module is that the level of difficulty increases as the test proceeds from the first section to the fourth section, the fourth being the most difficult of all the sections.
Even a slight mismanagement or a lapse of concentration can make you lose the sequence of questions and panic sets in fast, and this may lead to heavy loss.
On the contrary, if you get stuck up at a question, you give least attention or no attention to rest of the recording, as a result of which you cannot answer rest of the questions.
For instance, at first, the speaker may say "I will come this Wednesday" and then he may change by saying "No, no, I will come on Saturday."
Here the right answer is “Saturday” and not “Wednesday.” Hence, be more careful when listening to such conversations and make sure you write the right answer.
