Hello Aditya,

Hope you are doing well.

The only prerequisite to be eligible for applying in Government jobs and Defence services is the age criteria, which is different for different types of services and that the candidate should be a Graduate (In any course).

Other than this in almost all Defence services, having Math and Physics as your subject in 10+2 is also a necessity.
