The conclusion is where you sum up what you have said in your essay. It is absolutely vital – never fail to write one. This is the last thing an examiner reads and counts for a great deal: a good conclusion can rescue an indifferent essay and set the seal on a good one. It is here that you draw together the threads of your argument and hammer home your points, leaving the reader in no doubt as to your answer. You should refer explicitly to the key words of the question and reinforce the points you made in the main body. Above all it should contain nothing new – it is simply a restatement of your argument. If there is anything you have not already said it is too late now!
Overall, this is an excellent start to a compelling essay. Keep in mind that although the committee allows you to write up to five pages, three double-spaced pages is usually adequate. Feel free to add more detail, but make sure your text is concise and transparent. You might consider "writing" ideas and then "rewriting" them. Too often, authors put ideas onto the page, but do not render those ideas compellingly. Giving your sentences a bit of extra effort, and giving your experiences a bit of extra reflection, will result in a persuasive essay that compliments your accomplishments and character.
