If you are currently still under National Service you don't have to. They will only send you for NPCO course in TRACOM if you did that i don't think so. But if you ORD more than 3 years if i'm not wrong than you will have to so called re-take everything like a Trainee. =DOriginally posted by DaoMilky:Do we need to go back tracom if u now a SC n u went thru all e interview of Junior Officer?
