I am doing my engineering in electronics & communication engg. (III year). I want to join Indian army. Would you please suggest me on how to go about it. Also can you give me details of CDS exam and some books useful for the exam. I have NCC 'A'. certificate. Can I get any benefit as a son of an army personnel. My father is still working in Indian army as a J.C.O. (subedar major). My date of birth is 26 December 1981.
