Finally, you will write a short conclusion which reminds readers of your main argument and summarizes the way in which you have supported that argument, adding strength to your position. In some essays you will include additional material to the conclusion, for example pointing out areas which still require research or the limits of your own research, but this is something to discuss with your tutor or study skill support staff who are teaching you how to write an essay.
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.
