hey!

after medical exam, you will have to wait for merit list. if your name is there in merit list then you will get the call letter to join in nda. after reporting, you will be given your service id, rooms, squadron, uniforms, badges and you will be said about all rules and regulations.

then you will have your meals with your seniors, then you will have

RAGDA. and other training stuffs. then you will have your timetables and regularities. this is how day 1 in nda looks like

i hope you found this helpful
