Examine your topic. Look at the keywords. Have you been asked to discuss, or examine, to compare or some other process? Make sure you know the difference. What are you being asked to write about?
Brainstorm all your ideas.
Using this prepare an outline or diagram of your ideas in relation to the topic.
Write down what you know, and what you need to find out.
Do any research, making sure you record references for all information you have found.
Write your thesis statement. This is the one sentence statement that summarises what you are saying in your essay.
Write the body.
Write the main points.
Write the subpoints. Remember you support your argument by evidence or logical reasons. A strong reason logically supports your point and is specific and states the idea clearly.
Elaborate on the subpoints with further description or explanation or discussion
Write the introduction. Now you've written the main part of your essay you know what to say in the opening section. Begin with something to grab the reader's attention: an anecdote or some startling information. Use a few sentences explaining your topic in general terms, then gradually become more specific, until you reach your thesis.
Write the conclusion. Now you've written the rest of your essay you know what to say in summary. These are three or four strong sentences summing up your points or providing a final perspective on your topic. Review the main points (being careful not to restate them exactly) or briefly describe your feelings about the topic.
Add the finishing touches, checking flow, word and sentence order, spelling and don't forget your reference list!
