Planning your essay involves organizing your ideas into a logical order. You can do this by creating a mind map or by making a list of headings with bullet points under each. Your essay needs to be well structured. You will need to write an introduction which explains what you are writing about, introduces your central idea and the point of view you plan to support. Then you will go through each of the relevant points, linking them in a way that flows and makes sense of the topic.
There are many different essay styles and it is crucial to know what is expected of you. Universities, colleges and individual tutors will tend to have their own preferences and so it is important to make sure you know the right formula for your course. You can find a lot of information to help you online, but do check everything with your tutor or writing support tutor before you go ahead with writing your essay.
