Word limits are there for a reason. They reflect the scope of the assessment exercise. Essay questions are devised with a word limit in mind, and you should be able to produce a highly effective answer without straying beyond this. If you find that you have difficulty keeping within the word limit, talk to your tutor. It may be that you have misunderstood the question, you are including irrelevant detail, or simply straying from the main point. Learning to write to a specific word limit is a valuable skill to acquire.
You should aim to produce a well-structured argument, expressed in clear and economical prose. It may be tempting to assume that the more you include in your essay the more likely you are to achieve a good mark. You have a 10 per cent margin above or below the word limit before you are penalised.
Your word count should be taken as it appears in the file you submit to Turnitin and by hard copy. Please note that once your essay is uploaded, Turnitin may display a word count that is incorrect.
Word limits may vary from module to module and you should always check the module outline for module specific information.
