I don't think I did too well this time on AWA. Perhaps 4.5 or so. I just had nothing to say on the issue analysis but I'm sure I rocked the argument part. Make sure that you take the breaks after this as it will give you the final breath before the "real" thing starts. I wasn't happy with how the issue part unfolded but never looked back or even had any thought about that in the following sections. I would recommend you to stick to a combination of PR/OG templates as it works with just any situation. Last time I stuck with those I got 5.5. I think that as long as you got 4+ and a good GMAT score, AWA should not be a major concern. Don't sweat it.
I ended up having 5.5 in AWA. I don't know about the company you mentioned but I suggest you to stick to templates. It's the safest way to score well for non-native speakers
