GMAT Essays (AWA)

Now, I have never ever written a single essay since 10th grade. And I am pretty close to taking the test (have not taken a date yet but I feel I am 4 weeks from writing it) and I have been writing mock tests by skipping AWA sections.

So far, so good.

But now, I am a bit worried and I wanted to know if I there is anything I should go through which provides some strategy for approaching arguments and essays and some samples too.

I have OG11, Kaplan (some book - didnt feel the need to open it yet).

Please provided me any references such as online links, downloadable documents or book recommendations.
