To finish your essay you will need to write a conclusion. In your conclusion, you are required to reiterate the main points or revisit the key themes that you have discussed in the main part of your essay. A good conclusion should not contain any new material as it is likely to leave your reader wanting more and you will not have the space to discuss additional points in detail. Therefore, all the points you mention in your conclusion should have already been discussed in the main body of your essay. See WritingConclusions.pdf for more details.
