In most circumstances, your assignment will specify the quantity of words or pages you are required to produce. This is frequently a range rather than a specific amount (for example, 2500–3000 words or 10–12 pages). Always consult your teacher if you are unsure. The length of your assignment will usually be specified in words or lines. One word equals one horizontal space when printed. So, a page that contains 11 sentences with a total word count of 5000 would be about 5 inches by 7 inches. At 12 points font, this would be about 66 characters per line. In addition to these measurements, assume that an inch of margin space on all sides of the paper will be included in your word count. This is important when submitting work that has been typed up on a computer; please check with your instructor regarding any special instructions regarding margins and word counts. Generally, writing assignments should be confined to one single topic and should take up no more than 15% of the total exam score. Any more than that and you risk being penalized by reducing your overall grade by half a point for every 1% over the limit. Some assignments may require research. To reflect this, some universities give a percentage increase in their assignment price for each level of qualification held.
