Create an outline: Map out the rough structure of your essay in an outline. This makes it easier to start writing and keeps you on track as you go.
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.
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.
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.
Some students react to the time pressure of essay exams by scribbling down their introduction as soon as they`ve read the question and figuring out their points as they go. While it might seem counter-intuitive, taking five or ten minutes before you start writing in order to draw up a plan will be an enormous time saver.
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.
