These are some general tips you can follow to improve your IELTS LISTENING Task 1 and IELTS LISTENING Task 2:

    Don't just glance at instructions; read them carefully. They can vary considerably.
    It often happens that the speaker will give you an answer and then correct what s/he has said - watch out for this ploy.
    Try to anticipate what the speaker will say. This requires concentration - easy in your own language, but more difficult in English !
    Although there are not that many IELTS books on the market, other Cambridge exam preparation materials can provide valuable practice; for example, FCE and CAE preparation books.
    Small errors can lead to a low score: spelling mistakes, omitting plural 's' or incomplete time indications.
    Don't panic if you think the topic is too difficult or the speaker is too fast. Take a deep breath, relax and tune in.
    Read, write and listen at the same time. Tricky, but worth practicing!
    Don't leave blanks - you will not be penalised for wrong answers so you might as well guess !
