It is easier to write an excellent essay than you might think. First of all, your essay should be focused on the question proposed. This means that you should read the question carefully a number of times, picking out key terms and considering various approaches. It may be tempting to try to redirect your essay to a subject that more fully exploits what you think you know best, but this will usually be perceived for the evasion that it is. Second, your essay should be organized and coherent.
Organization means that the parts of the essay are clearly demarcated and logically connected.
Coherence is a question of transitions from one part to another and the compatibility of your different assertions. The only way to be sure of producing an organized, coherent essay is to plan it in advance. As you do so, consider whether the parts fit well together into a whole and also anticipate how you'll make transitions from one part to another. As you work on your plan, you may notice other students scribbling furiously and worry that you are getting behind. Third, your essay should be both general and specific.
