Hi already took the exam in 2004 its quite a bit difficult. There are 2 types, academic and general training. The academic is much more difficult than the other. There are 4 areas to be tested 1. Listening - you are given an answer sheet which you will complete/fill-in. 2. Reading --- u are given 3 short topics (eg climate change). Every topic has questions to be answered. (this is the part that is somewhat difficult because u have an hour to finish the task. 3. Essay writing.2 task (eg graph/pie analysis) etc. 4. Speaking interview, question and answer.

For my opinion you should review in a good review center. Developed a way on how to tackle each areas to be tested.

Good luck on your endeavors.
