Hi kimywittmer,
first, let me say I'm not an expert, since I am also preparing for the test myself -temptative test date is November 26-.
Your essay is clear and well structured and you provide many examples. I think overall it would be a 5.0.
Here are a few remarks that I'd make:
1) Be careful of idiomatic expressions: you use "resulted to", where the preferred expression is "resulted on"
2) Try to avoid coloquial expressions such as "a lot more convincing". Try instead "much more convincing" or "considerably more convincing"
3) This is not a correction, but an open question to you and/or any others who might come accross this thread:
you say
"After all, readers buy newspaper not just because of its lower price but most especially because of the important news and features that they could gain from it.",
which I believed is a subjective statement, based on your opinion. Are such personal opinions expected/accepted on the AWA or should they be avoided?
I hope I've been helpful, please give me kudos if you thought so! I'll appreciate it

Cheers, and best luck on your preparation!
