Outlining your first draft by listing each paragraph's topic sentence can be an easy way to ensure that each of your paragraphs is serving a specific purpose in your paper.
You may find opportunities to combine or eliminate potential paragraphs when outlining—first drafts often contain repetitive ideas or sections that stall, rather than advance, the paper's central argument.
Remember the “Rule of 3” which states that you should find 3 supporting arguments for each position you take.
Start with a strong argument, followed by a stronger one, and end with the strongest argument as your final point.
This is why you should establish early on the scope and limitations of your paper which will provide the foundation for your research paper outline.
Basically, your outline will constitute three main sections: the Introduction, the Body and the Conclusion.
Each major point should advance the paper's central argument, often building on the previous points, until you have provided enough evidence and analysis to justify your paper's conclusion.
More Major and Minor Points: In this paper, more major points might include mental health of high school dropouts, healthcare access for dropouts, and correlation between mental and physical health.
The conclusion is where you form a summary of all your arguments so you can arrive at your final position.
Explain and reiterate why you've ended up with the said conclusion.
