Suggest you retake GMAT. Even if you apply PHD, the competition of top schools is very tough while many from top university of china also eqipped tremendous academic awards. With your overall situation, going to a avearge school makes no sense to you.

So you may reconsider your decision and make a feasible arrangement.

For PHD, it is really late for you to catch the best round. To improve 540 to 700 is also not so easy...

But first, you have to make sure what you really want? Academic or professional? Both choices are investments of time and money; both are not casual for us who are not so younger..

Hope this helps.
