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.
In longer essays, you can end the introduction by briefly describing what will be covered in each part of the essay. This guides the reader through your structure and gives a preview of how your argument will develop.
The introduction sets the tone for your essay. It should grab the reader`s interest and inform them of what to expect. The introduction generally comprises 10–20% of the text.
You should formulate your thesis statement—the central argument you`re going to make. The thesis statement provides focus and signals your position on the topic. It is usually one or two sentences long.
After the topic sentence, present evidence such as data, examples, or quotes from relevant sources. Be sure to interpret and explain the evidence, and show how it helps develop your overall argument.
When composing essays, many students stop and read over each paragraph once they finish it, making sure that it`s well-written and free of errors before advancing to the next one. This approach is entirely logical when there`s no time pressure involved, but it can actually work against you during an exam.
