Your best supporting idea – the one that most strongly makes your case and, simultaneously, about which you have the most knowledge – should go first. Even the best-written essays can fail because of ineffectively placed arguments.
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.
Take note of the amount of time allotted for the exam and split it into reasonably-sized segments, leaving some time at the end for revision if possible. Without a schedule to follow, it`s easy to become too focused on a single paragraph and run out of time to finish the essay.
If you did your best to write a complete, clear, and insightful essay within the time allotted, you should have nothing to worry about.
Decide on your thesis, the topic of each paragraph, and the arguments which you intend to cover, then jot down some quick point-form notes. This process won`t take long, and, once you complete it, all that`s left will be to expand those notes into a well-organized essay.
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.
