The only IELTS exam I am familiar with is the International English Language Testing System. It is an exam that gauges how well a test taker communicates in English. Listening, reading, writing, and speaking are all covered. Is this the test you are referring to?
If so, I suggest searching the internet for IELTS; there are a number of online study guides and practice tests to help you prepare for the real thing. Also, you could talk to your academic advisor (if you have one) to see what resources they have to prepare for the test.
I hope this helps!
