ascendas is a kind of small bus, some r in green color, and some, blue + white. it's the same size as the shuttle bus that travel between NUH and Bouna Vista. only difference is that, in the front, there will be the characters 'Ascendas X(1,2,3....)'.

call the bus, tell it where u r, how many ppls u got, and where u r going. (it would stop only at 2 stops in NUS. they r centre lib & LT29). it will tell u that the bus is coming at ...time, and it is bus1 or 2 or 3.....

BTW, r u going to SP I or II?
