This is the way to do it! I have done it at Maju Camp. So please do take note, only FCC are monetary and not the convenient SAFRAs near your home.
How to do it?
Booking of Individual Physical Proficiency Test (IPPT)
Go to ns.sg portal, log in via SingPass or NS Portal ID. Choose your favourite FCC, your convenient date and train for it!
Each IPPT session easily have more than 100 participants. Therefore, do expect queues at the station and detailings for the 2.4km run.
Show your Identification Card at the IPPT counter inside to receive your Number Tag. The card holder behind is for your Identification Card. The changing room is just located beside the counter. The IPPT stations in Maju Camp are electronic systems.
