From where?
NUS Biz-sch is also accessible from Pasir Panjang Rd, but
there's a nice long steep slope in the open that could be avoided.
It depends on exactly where you are headed within biz.
You could take 95 from Buona Vista MRT, and then drop at the
central library, and take A, B or D to Biz.
am coming from kallang/town - planning on taking the MRT; i
remember stopping at BV station the last time and then taking the
bus. but this was to the stadium/field. so not sure if i should get
off at BV since i've zero clue where the b-school is.
