Analytical Writing Assessment (AWA) | Re: How to improve AWA?

Essay is good, on the topic and on a first read I did not spot significant grammar errors (this can impact your score). In fact, language used is really good. I'd say >= 5 but there is no reason why you should take my opinion seriously.
But really, it's been said many times, there is no reason to overdo it, study for Verbal or Quant instead.
