I would recommend reading this article: how-to-get-6-0-awa-my-guide-64327.html
This article will teach you how to put a template together to help with the essay.
Then I would also read this article to help give you an idea of what AWA essays will look like: awa-compilations-223-essays-86274.html
This will give you everything you need to know. Other than that, practice practice practice. You just need to do well enough to get a decent AWA score (4.5 or above).
