A university』s reputation is built around factors like academic course structure, career opportunities, research output and the presence of alumni in reputed organizations among several other factors.
Singaporean universities are ranked high in some international rankings, but it may not linearly translate into an equivalent level of career opportunities for the students. For example, if a student wants to work at the Intel』s chip fabrication plant in Portland, a degree from a local university in Oregon or some other university in the USA will offer a higher level of opportunity in comparison to a degree from Singapore.
Another key aspect of Singaporean universities is that, they started investing in research seriously, only in the last 20 years. Prior to that, research was not a high priority for them. The result is that, you would not find many alumni from the universities in Singapore as CEOs of global companies or as faculty members in leading universities of the world. Currently, there are some groups in NUS and NTU, which are well known internationally and their reputation is slowly finding traction. But the density of original inventions and discoveries with their origins in Singapore still remains relatively low in comparison to many universities in the West, whose overall rankings are low.
The third aspect is the universities in Singapore are still working hard to translate their education and research output into entrepreneurial ventures. The number of companies with global footprints with their origins in Singaporean universities are not that high. In contrast, you will find that apparently unknown universities in many countries in the USA, UK and elsewhere, have been cradles for great technologies and companies.
The fourth important aspect is the hot and humid weather of Singapore is something which even Singaporean do not admire much. They are keen to spend some time in cold countries.
To sum up, in a school setting, there could be a linear relationship between marks which you get and your knowledge and admission prospects in future. The linearity breaks down completely in the context of a higher education, where, international rankings may not have a direct relationship to job, career prospects and overall student experience.
