First of all get some books about IELTS which has mock exams in them.

Take a mock exam every day that will definitely help you out so you can manage your time well.

After that from now on whenever you here a new word look at the dictionary so in this way you would know its meaning and also spelling.

In your spare time listen to tapes and watch movies.

You could also practice your speaking skills in that way as well as you could speak with yourself predicting what the examiner would ask you and what your answer would be.

This is what I did and got an overall score of 8 with 2, 8.5 in listening and reading a 7 in writing and an 8 in speaking.

This is how you could get ready for the exam.

But in the exam date:

in the speaking test you should know that the examiner will try to relax you down because they know that everyone are nervous about their exam so just try to cool down as soon as you can.

you should know that the important thing for the examiner is that he or she just want to know how you speak and how you could communicate with other people so don’t get nervous if you think you could have answered the question in a shorter form it is not really important for them.

Don’t get worried if you thought you have said a wrong word just go on as long as you could tell what you mean although you might have used wrong word is enough and you have got nearly the full marks.

at the day of other exams just be relax and try to concentrate on your exam listen good and you would have no problems as long as you have practiced hard in the remaining time.

GOOD LUCK on your exam
