In your essay you need to identify that goal. Give an explanation of how you plan to accomplish this goal. You should use your personal observations, expertise and skills to support your essay.
Don’t forget to add details and develop your ideas. Pay attention to sentence structure and avoid spelling errors.
Stay at the topic, and do not shift to less relevant subject areas.
Your essay must include a number of (preferably five) paragraphs where you explain to some detail how you reached your topic or conclusion.
You should begin with a clear main idea and support this main idea with three relevant paragraphs. End with your conclusion and use precise words.
Here is another example of a simple error of omission that could have been caught if the student had read the essay aloud or given it to a friend to read. The word "of" should be between "calculation" and "the." That one small error makes the entire sentence awkward and confusing. If the instructor has to reread the sentence to try to understand its meaning, the flow of the essay is interrupted. If this happens often enough in the essay, it gives an overall bad impression on what otherwise might be a very good paper in terms of research.
