If you've been tasked with an argumentative essay,
Start by writing the thesis statement at the top, and then write a topic sentence for each paragraph below that. This means you should know exactly what each of your paragraphs is going to be about before you write them.
Don't jumble too many ideas in each paragraph or the reader may become confused.
Ensure you have transitions between paragraphs so the reader understands how the paper flows from one idea to the next.
Fill in supporting facts from your research under each paragraph. Make sure each paragraph ties back to your thesis and creates a cohesive, understandable essay.
