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.
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.
Understand your assignment: What is the goal of this essay? What is the length and deadline of the assignment? Is there anything you need to clarify with your teacher or professor?
If you realize that you`re falling dangerously behind schedule, it might be necessary to cut some arguments or examples you planned to include. Although making these omissions can be painful, it`s better to leave out a few points from one section than to leave out an entire paragraph because you ran out of time.
Before you start writing, you should make sure you have a clear idea of what you want to say and how you`re going to say it.
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.
