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.
In the end, then, one thing is clear: mistakes do far more to help us learn and improve than successes. As examples from both science and everyday experience can attest, if we treat each mistake not as a misstep but as a learning experience the possibilities for self-improvement are limitless.
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.
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.
Although it may seem like a waste of time – especially during examswhere time is tight – it is almost always better to brainstorm a bit before beginning your essay. This should enable you to find the best supporting ideas – rather than simply the first ones that come to mind – and position them in your essay accordingly.
On the topic of planning, it`s important to sketch out an idea of how long you want to spend on each section of your essay. If you know the number of paragraphs you`ll need to write ahead of time, you can do this before the exam even starts!
