 Which are important for IELTS speaking? Eye contact, body language and hand gestures are not considered by examiners at all because they have no contribution to how you can effectively speak English. Also, the examiner does not care how you greet them or what clothes you wear. They do not care if you wear a bin bag or you wear a three-piece suit. They don't care if you greet them politely. All they care about is your ability to speak in English. Using lots of idiom does not help you clearly communicate with the examiner. The examiner is not assessing how many idioms you use, but whether you use them appropriately or accurately. You can get a bad nine and use zero idioms. The examiner also doesn't assess which accent you have. You don't get extra marks for having a British accent or an American accent. The examiner is assessing how clearly you speak, not which accent you have. Only thing the examiner cares about is did you clearly answer each question. If you focus on this and this only, you will be way ahead of most students who focus on all of these things that do not matter.
