It is definitely better to have a full-time MBA. On-the-job students usually attend classes at weekends or evening classes, which will inevitably affect the quality of courses and challenge your physical strength. Moreover, the MBA of the Hong Kong University of Science and Technology is definitely better than the ordinary MBA in Shenzhen, and the gold content will be high.

I suggest you set your goal within two years. First, because IELTS and GMAT are valid for two years; Second, if the front line is stretched too long, people will easily be lazy.
