問題的關鍵是, 能不能拿到不是騙錢的大學的錄取呢?
First you have to persuade them that you can handle the study, and you bachelor (2本 + GPA) is definitely a very bad signal.
There is nothing much you can do about this, except getting a good GMAT (for sure 660 doesn't count as a good one in Chinese applicant)
Another more reasonable plan is to use a good working experience to support your application, instead using your weak academic record, i.e. go to find a job and work a few year first.
