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.
Therefore, if you take the time to review your notes and ensure you understand everything that was discussed, it should be difficult for the essay question to catch you off guard. As soon as you read the question, relevant course concepts will start popping into your head, and you`ll just have to organize them into a coherent essay.
If you did your best to write a complete, clear, and insightful essay within the time allotted, you should have nothing to worry about.
The body of your essay is where you make arguments supporting your thesis, provide evidence, and develop your ideas. Its purpose is to present, interpret, and analyze the information and sources you have gathered to support your argument.
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.
Once you hand your exam to the professor, relax! It`s easy to work yourself up after an essay exam when you didn`t get the chance to read your work over or you feel like your arguments were weak.
