Tuition grant, how much did we give away?

Png Eng Huat asked in Parliament and the MOE gave its reply. $210 m were
given to international students as tuition grant annually. Presumably
or assumingly this is the average sum, so in 10 years it will be $2.1b
and 20 years it will be $4.2 b.
 
There are several questions to this figure. Is it just for tuition
grants and excludes living allowance and others, or is this the total
package
