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.
To give your essay a clear structure, it is important to organize it into paragraphs. Each paragraph should be centered around one main point or idea.
This tip may seem basic, but it`s easy to forget and it can make a big difference. Both these measures won`t just make it easier for the marker to read your paper; they`ll also help you write it. If you have time left at the end of the exam for review, having the ability to skim quickly through your work and write revisions in blank spaces will be incredibly helpful.
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.
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.
