BG一般的申请人,不申请美国的都挺头铁的。建议先抓紧把GT都考出来个正常分数,然后到了HK混个part time RA作为中国申请人标配,想读哪个专业就去混哪个专业的RA,这样一封推荐信到手。至于推荐信的质量就看你干活的给力程度和老师的标准了。然后你就把你能看得过去的非美国学校都投一遍,然后最后能去哪里去哪里吧。
To my opinion, the 1-year CS master program of HKU can hardly boost your chance of getting accepted by a business PhD program.
I would recommend you apply for 2-year business master programs of Chinese University of HongKong-Shenzhen.
