I plan to study my degree in NUS but how much does it cost per year? What does Tuition fee mean?
Tuition fee is the "school fee" that cost about S$30,000ish a year, depends on the course you are applying.
You can apply for a tuition grant with 3 year bond in Singapore, it is a subsidy program and you only pay around S$6000-9000 a year (also depends on the course you take and whether you are foreigner/PR/Singaporean).
On top of those, you can apply a few scholarships available. Depends on the type of scholarship, you may not be paying any of the amount stated above, and even get some pocket money, but may have additional bond years.
Take a look at the university website for more info


good luck!
