Personal experience, similar in terms of magnitude but not much else. I paid roughly RM400k for my education this year, this is an MBA from a top 5 b-school. I'm not however taking a lot of loans and I expect my ROI to be less than 3 years.

As much as I think UCL will be better than NUS, paying RM400k for an undergrad degree is a lot and taking it all as loans is risky as hell. I agree with a lot of what's been said here, particularly dreamer. Your undergraduate is not the most important step in your educational journey. Do your undergraduate at NUS, get some work experience, then spend that RM400k on a top notch MBA. You'll make your money back in no time.
