GMAT AWA Score - Slightly Worried

Hey all,

I took my GMAT for the 2nd time last week. While my overall score improved, my AWA score is pretty low. My scores are:

710 (Q47 V39) IR - 8 AWA - 5
750 (Q48 V44) IR - 5 AWA - 4

My score both IR & AWA. AWA especially, is the 18th percentile, which is really worrying. Under other circumstances I'd ask for a re-score, I'm fairly sure I can write better. But in this specific case it was the last section of my test and I just wanted to get it over with and possibly did drop the ball by being careless (don't do this if AWA is last for you, it really dampens your mood after a good score).

Do you think this drop, and particularly the AWA score is cause for concern? Both scores are reportable, so schools can see them both. Non-native speaker from an over-represented demographic if it makes a difference.

Thanks for any replies!
