How do I structure my argument in an essay format?

Break down the key words in the question; are they asking for A01 & A02, or just one? Make a plan, firstly deciding which side of the argument you lean more heavily upon (if you don't have an original preference, lean towards whichever side you have more evidence for). Write an opening sentence for the introduction and a closing sentence to link everything previously stated for the conclusion. Outline each paragraph of the main body for the essay (approx 5) with the opening key sentence, the evidence supporting and your link to the question. It's personal preference, but I would follow the introduction with a paragraph arguing my side. Then I'd follow with a paragraph opposing that view, shown through the opening of 'on the other hand'. Then I'd go back to my original viewpoint in the next paragraph, weakening the previous one's argument. This would be my structured debate on the page.
