Glad to see fellow Sarawakian doing well here!!

Hi, I presume you are from Johor City since you mentioned JB. If so, you can take either the yellow bus (CW bus) from there to SG, and alight at Kranji MRT. Alternatively, you can take bus 170 (SG bus). Ask around if you ain't sure at the custom there.

From Kranji MRT, you can take the train to Jurong East, then transit to Joon Koon Station and alight (you will need an ezlink card for this, can be bought at the counter or nearby 7/11). Take cabs to the destination from Joon Koon station.

However, if you are coming to SG from Nusajaya/ Bukit Indah or somewhere near to 2nd link, you can take the CW bus from Giant at bukit indah (CW 3 to Jurong East or CW 6 to Boon Lay). From Giant, just hop to any of the CW buses to SG, as u can switch the bus to either CW 3 or CW 6 after u pass the SG immigration. I will advise you to take the CW 6 bus from there, and alight at Boon Lay then take cab from Boon Lay to your destination.

Hope the above helps.
