You Started at the Beginning
This seems like a ridiculous proposition; of course you start at the beginning, right? Well, not exactly. As a TA, I marked hundreds of essays and the vast majority had an excellent introduction. After that, things tumbled downhill quickly. If you start with your introduction, you’ll edit it over and over, every time you read your paper. It will shine, but the rest of your paper will suffer and you’ll waste valuable time. Leave the introduction until the end, then write it at the same time as the conclusion. The introduction and conclusion are connected and are meant to be written after your evidence has been presented.
