Hello.

May I know if anyone knows the average starting salary for M.Sc. in Finance graduates from NUS? The FT ranking shows the salary data only for MBA and EMBA from NUS, so I cannot find the salary data for the NUS MiF anywhere.

Thank you !

Did you consider searching Google and clicking on the first link? https://www.google.com/search?q=starting+salary+for+M.Sc.+in+Finance+graduates+from+NUS&client=ms-android-ee-uk-revc&sourceid=chrome-mobile&ie=UTF-8

Of course sir, I did. As it was stated as a 'sample' salary, and as I'm
not quite familiar with that website, I'm a bit uncertain about the
outcome in reality. I saw that Singapore Management University's (SMU)
average salary is around 60k according to the FT ranking. Can NUS be
higher than that perhaps?

It could be. It's based on a sample, as any quantitative research is, but it's a start. 
Why not ask the school directly?
