450 words minimum to 550 maximum in exactly five paragraphs. If your essay falls short of or exceeds the required word count or if it does not follow the required paragraph-count, the grade will certainly suffer. Moreover, the word-count requirement refers to only the words in your paragraphs, not the title or any other part of your essay.
Your introductory paragraph should introduce your topic without engaging in any argumentation, and its final sentence must be the thesis statement; the three body paragraphs are where the argument should take place. The conclusion paragraph should tie everything together.Regarding the proper length of paragraphs, at a bare minimum, each paragraph should take up at least five lines on the page.
