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.
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.
Without a clear plan, you run the risk of realizing partway through that you`ve drifted off topic or written yourself into a corner, and fixing these mistakes will consume a ton of extra time.
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.
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.
It`s important to give context that will help your reader understand your argument. This might involve providing background information, giving an overview of important academic work or debates on the topic, and explaining difficult terms. Don`t provide too much detail in the introduction—you can elaborate in the body of your essay.
