Hey Sou Vongvisal,
It is not so difficult to get a high score on the Speaking test if you do some preparation beforehand and you stay confident and relaxed during the test.
There is lots of advice on this forum, under Speaking, including past experiences of other students who have taken the test already. The hardest part for most students is Speaking Part Two ( Long Turn ) where you must speak by yourself on a topic for between 1-2 minutes. This can be difficult if you have had no practice. Ask your teacher to let you have a practice in class and ask him for some feedback and some ways you can improve your overall speaking skills. :lol:
Being positive is the main thing, and believe you can get a high score means that you have a much better chance of achieving it. You become more confident and less nervous when you are with the examiner in the test room.
Here are some basic skills you need to be practising:-
Speaking Part One - you need to give full answers and some expansion, that means giving a bit more information. See the IELTS secion in this website ( click on IELTS on home page ) and you will see more about this.
Speaking Part Two - You need to have good ideas and a clear structure to your speech to make it sound effective.
Speaking Part Three- You need to develop the English skills to be able to -make suggestions, give opinions, state preferences, predict the future and compare and contrast.
Hope that helps,
Have fun, :wink:
