If you did your best to write a complete, clear, and insightful essay within the time allotted, you should have nothing to worry about.
The body of your essay is where you make arguments supporting your thesis, provide evidence, and develop your ideas. Its purpose is to present, interpret, and analyze the information and sources you have gathered to support your argument.
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.
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.
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.
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.
