To get an A on an essay, do quality research and formulate a good thesis statement. Also, write an outline that will guide your writing and start your essay. At the end, cite reliable sources of information and adhere to the format required before proofreading the paper thoroughly to check for errors. An essay should be structured on three parts. The introduction where what the essay is all about will be presented. The body paragraphs where all the arguments will be fully discussed and the conclusion where the essay will be summarized.
