If you did your best to write a complete, clear, and insightful essay within the time allotted, you should have nothing to worry about.
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.
After the topic sentence, present evidence such as data, examples, or quotes from relevant sources. Be sure to interpret and explain the evidence, and show how it helps develop your overall argument.
You should formulate your thesis statement—the central argument you`re going to make. The thesis statement provides focus and signals your position on the topic. It is usually one or two sentences long.
To give your essay a clear structure, it is important to organize it into paragraphs. Each paragraph should be centered around one main point or idea.
That idea is introduced in a topic sentence. The topic sentence should generally lead on from the previous paragraph and introduce the point to be made in this paragraph. Transition words can be used to create clear connections between sentences.
