The first stage is to decide on 3/4 major points that you will be writing about. These points can each be focusing on a character or a different theme, as long as each point is unique and adds to the overall question. For example if asked a question about the portrayal of women within Gatsby, one might have one point on the suppressed nature of Daisy and Myrtle, another on the superficial and shallow nature of women such as Daisy, and then perhaps a final point on the cold and manipulative behaviour of characters such as Jordan.In writing these points in an essay one must always keep in mind the assessment objectives (e.g. close literary analysis, context etc) This is the basis on which an examiner gives an essay marks. If an essay has 20% of its marks towards context, ensure that each paragraph has 1/2 points of context. While writing each point, always keep in mind the assessment objectives and that you are ticking the boxes required for the examiner to give you marks. Your introduction should be a summary of the overall argument that links all of your points together, and your conclusion should show how all of these points have built on each other to create that final argument.
