Hi again,
Good questions. So I think there's some truth to the first myth...there are more and more GMAT tests being taken by applicants in China (and India too) and it is starting to skew scores upwards because these applicants do tend to outscore applicants from many other countries, especially on the quantitative section. So it doesn't mean that you have to have above average scores...remember that it's a holistic admissions process so just having above average scores is not a guarantee and on the flip side, having a stellar application with slightly below average scores is not a dealbreaker. Since you're applying from a competitive demographic, standing out in other ways (beyond just test scores) is important too. For a related perspective, check out this WSJ article:

But I have heard that it's less common in some countries for employers to be willing to write recommendations. We highly advise that you don't write your own, it can be really hard to write honestly and objectively about yourself and it's hard to mask your style of writing too.
Hope this helps and good luck!
