To pass your IELTS Letter Writing you need to be able to write a letter of over 150 words in about 20 minutes. In order to achieve a high-score you must prepare for your test well.  I have summarized the main ways to prepare effectively below:

1. Understand the writing test requirements, including grading
2. Learn how to write the different types of letters that get asked
3. Build up vocabulary for letter writing
4. Read model answers to past questions to see how you should write your letters
5. Start writing letters under test conditions. You need to be able to write your essay in about 20 minutes.
6. Get your tasks assessed by a tutor who has trained as an examiner.
