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.
The most important part of writing an essay exam is ensuring that you`re answering the question was posed. Even if you made sure you were interpreting everything correctly before you began, you may have forgotten to address a subquestion or integrate an example as you were writing. Before you submit, read the prompt again and make sure your completed essay matches up!
Start planning if you can. Although the situation described above sometimes occurs, it`s also very common for professors to give their students a fairly detailed idea of what an essay question will involve in advance of the test day.
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.
In the end, then, one thing is clear: mistakes do far more to help us learn and improve than successes. As examples from both science and everyday experience can attest, if we treat each mistake not as a misstep but as a learning experience the possibilities for self-improvement are limitless.
However, it`s important to keep in mind that your professor understands the circumstances under which the essay was written. They`re fully aware of the time pressure you were dealing with, and they will judge your work far differently than they would judge a typical essay with a deadline set weeks after the assignment date.
