Having a good outline, you should start composing the chapters of your paper. You may start with body chapters, like “Methodology” and “Results,” for example, so that it’s easier for you to craft a good introduction and conclusion later.
Once the body of your paper is written, you should check each subchapter for mistakes and inconsistencies. Make sure to eliminate all grammar errors and rewrite paragraphs, sentences, and phrases that sound awkward, ambiguous, or irrelevant to your topic.
The last step is to make sure that your paper meets the requirements of the needed format. Craft a title page, create page headers, etc. See that in-text citations are formatted in accordance with the needed style too.
