i'm a student from singapore, and so i've gotten an offer from all 3 schools now, here's a brief description of both programmes by the universities.

University of Melbourne
3 year undergraduate programme in commerce, planning to major in accounting and finance.

Rotterdam School of Management
3 year undergraduate programme in international business administration.

Singapore Management university
4 year undergraduate programme in business management

I would like to get into Ibanking in the future, and possibly find employment in the country that i'm studying in upon graduation, hence i would prefer a uni that has a wider global outreach as well.

Which would you recommend?

How about either of the three year degrees, followed by a one year MSc? The Master of Science in Financial Economics at SMU looks interesting. I think a BSc and a MSc in a four year period is a better idea than only an MSc. And a BSc from a international university will be a valuable life experience.
