You don't need ticket to go Tekong

Just proceed to SAF Ferry Terminal. Reachable by taking Bus service 89.\
Reason you are being posted to HQ first might be because there are too few female recruits for now to conduct a BMT for you all.
So you all might be going to BMTC HQ to do some admin work.
When you reached the ferry terminal, proceed in and asks for direction from the RP. Most of the time they will direct you to the 'ticket' counter. Go there register with your IC and wait for your ferry to come.
The ferry service i think is 30mins once in the morning. Afternoon like 1hr once. not really sure the timing.
Upon reaching Tekong Ferry Terminal, just walk all the way straight and pass those RP, you will see a big big building. That's the BMTC HQ.
By the way, u signed on as what? Signals?
