Look at this post for advice on what not to do when taking the IELTS test.
1. Do not rush to answer questions
Candidates should take a second (or two) to think about what they want to say before speaking. So, you can quickly organize your thoughts and give a more comprehensive answer. By rushing to answer, you may not be able to answer the question correctly, or the answer may be disorganized and difficult to follow. Also, don't spend too much time preparing an answer that you think is correct, because there is no such thing as a perfect answer!
2. Do not answer the question you do not understand
There may be a question that you do not understand during the IELTS speaking test. In such a case, you can ask the examiner to repeat the question or explain a word. Please note, it's okay to ask for some clarification, but you can't repeatedly ask for it during the exam.
3. Don't be afraid to correct yourself
While speaking, don't be afraid to correct yourself if you realize you've made a mistake. This shows the examiner that you know you made a mistake and can correct it. Don't constantly try to fix every mistake, it's better to rarely correct yourself.
4. Do not memorize the answers
In no case do not memorize the answers! Having a pre-prepared robotic answer will not help you in the exam. The examiner will instantly know that your answer is memorized, which will affect your score.
5. Do not use complex words
Some candidates use “big” words when speaking and writing, thinking this is a good strategy. Although you want to show that you know a variety of different words, the words should be used correctly and should sound natural. If you use words, you don't fully understand, you may use them incorrectly, which can affect your speaking and writing scores.
6. Do not use grammatical structures that you are not sure of
Like the point above, don't use the grammatical pattern you're not entirely sure of. You should make sure you know how to use various grammatical elements correctly, such as verb tenses, transitions, conjunctions, and more. Remember, it's better to be safe than sorry, so don't use anything you're not sure about.
7. Saying and writing little (or nothing)
Make sure you speak during the Speaking test and what you write during the writing test! Remember, the examiner needs your speaking and writing to assess your language skills. Therefore, silence instead of speaking or space instead of writing will not help you or the examiner. This also applies to the reading and listening tests. Because answers left blank will be marked as wrong!
8. Don't forget to mention the main points
When answering questions for your writing and speaking test, make sure you get to the point. Don't repeat or phrase the question, add unnecessary details first, then get to the main point.
9. Don't let your nerves get you down
It's natural to feel nervous when taking any exam. To help keep your nerves in check, we recommend that you try some breathing exercises, take some time for yourself, eat enough before the exam, exercise, get a good night's sleep, and practice and prepare for the exam beforehand.
10. Don't Be Late for Your Exam
You should be there on time (early if possible) for your exam! Schedule your time to go to your exam venue, sign up, and sit and wait. Find out in advance where your exam is and how to get there. You don't want to start your exam by arriving late (or just a few minutes early). For most of us, this is stressful and distracting and not a good way to start an exam.
I hope you find these tips helpful and informative. Do not forget to take these into account when preparing for the IELTS exam! Good luck!
