I just got my official GMAT score and managed to get a 6.0 in AWA. This is my view on it:
- Make sure you practice AWA as part of your practice tests for the weeks leading up to you. It will help you build your mental stamina.
- Having said that, I found AWA can be used as a positive on test day. It eases you in after your AWA you will be comfortable in the test environment, your computer, your surroundings etc.
- I was a little worried about it but anyone who has written an essay in college can easily get a 6. Just follow the AWA guide posted on this forum.
In terms of significance, yes it has little to no bearing if your application is solid. I read that adcoms only look at it in rare cases. Nevertheless, until the GMAT is revamped we have to live with it and it's really not that hard so just read the guide and follow it and you should be fine.
