Many students (and some teachers!) have the wrong idea about what a band 7, 8 or 9 essay looks like. For example, a few people commented that they thought the essay in " IELTS Writing Task 2: independence question " wasnt good enough for a high score.
Please remember that the IELTS exam is a test for non-native speakers of English, not professional English writers. Its much easier than some people think to write a good IELTS essay. Dont try to use strange or difficult language; just keep it clear and simple, and try to develop your ideas so that you fully answer the question.
Some people wont want to believe me, but the essay in Wednesdays lesson would get a band 9.
