How long should your answer be?
There is no safe universal rule such as ‘a 12-marker is always three paragraphs’ or ‘a 20-marker must be a page and a half’. For a long answer, aim for enough developed writing to show the skill being assessed: several focused points, relevant evidence and explanation that links back to the question. The higher the mark tariff, the more development the examiner usually needs to see, but longer is not automatically better. A shorter answer that is precise, relevant and explained can be stronger than a longer answer that repeats ideas or drifts away from the task.
