Unless if you finished way ahead of schedule, don`t worry about major revisions like reorganizing the structure of the essay–it`s better to hand in an essay with an imperfect structure than a paper that`s impossible to follow because you had to stop halfway through the revision process.
Consider practicing writing under time pressure. You`ve probably written dozens of essays before–the only thing that sets a timed essay apart is that it`s timed. Students often struggle to complete the full essay within the time constraints, particularly if they have to write longhand when they`re accustomed to working on the computer.
For example, if you`ve been assigned a five-paragraph expository essay for a high school class, you`ll probably spend the most time on the writing stage; for a college-level argumentative essay, on the other hand, you`ll need to spend more time researching your topic and developing an original argument before you start writing.
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.
There are many types of essays you might write as a student. The content and length of an essay depends on your level, subject of study, and course requirements. However, most essays at university level are argumentative: they aim to persuade the reader of a particular position or perspective on a topic.
