Before you begin, make sure you know the word limit for your essay. You will usually be given a definite number eg 1500 words or 2000- 2500 words. If you are given a fixed number, it is usually acceptable to write 10% fewer or 10% more words. If you are given a range, try to stay within that range. However, check this with your tutor as you do not want to be penalized.
Brainstorming Once you have a firm essay title and are clear what it means, you can have a brainstorming session to come up with as made ideas as you can which relate to your essay title. If you have a lot of ideas, the next stage is to narrow them down to the most important and most relevant points.
