when the registration of this navy dssc started I quickly did it without wasting time, but after I've submitted my application, I started seeing some mistakes e.g I chose marine engineering and I studied physics. the father of all mistakes now was discovered yesterday which is that my application no starts with NN instead of DSSC, though I was trying to apply for that of O Level around august, but I didn't complete it. my question now us that is it advisable to start another registration as my mind is telling that I only completed the registration if that of O Level.
