Hi !!
First of I would like to say you that please don't get frustrated, be relax and never allow any problem to overcome you.
The second important thing is when you applied for ielts I believe you got a exam preparation book, ist it. If you get it then just practice that listening chapters and believe me you will be satisfied. The main important thing in preparing for listening is just CONCENTRATION- once you left any question unanswered move to next one but don't wait for that previous question, If you wait for answer for that previous question then the Audio Conversation will be moving to other questions and you will be shocked to see that the section is over in that Audio Conversation and you are struck in that old previous Question.
First Part and Second part of listening will be easy, just you will find difficulty in last part so, don't be afraid and be patience and believe in Almighty, do your hard work and leave on Almighty & Pray for me as I have test on 1st November 2014.
regards
