Although the conclusion paragraph comes at the end of your essay it should not be seen as an afterthought. As the final paragraph is represents your last chance to make your case and, as such, should follow an extremely rigid format.
Decide on your thesis, the topic of each paragraph, and the arguments which you intend to cover, then jot down some quick point-form notes. This process won`t take long, and, once you complete it, all that`s left will be to expand those notes into a well-organized essay.
Define a topic: If you`re allowed to choose your own topic, try to pick something that you already know a bit about and that will hold your interest.
If you have enough time left over, read your essay again and make corrections. When you`re working under time pressure, it`s easy to make grammar mistakes or produce hard-to-follow sentences; the final few minutes are your chance to clean up those errors.
One way to think of the conclusion is, paradoxically, as a second introduction because it does in fact contain many of the same features. While it does not need to be too long – four well-crafted sentence should be enough – it can make or break and essay.
After all, professors want to mark high-quality essays written by well-prepared students! This heads-up gives you a great chance to prepare for the exam. If you have the time, consider mapping out a possible essay in point form before the day of the exam arrives.
