My name is Arun Kumar and I live in Mahendragarh, Haryana. My father was in the Indian Army so from a very young age, I was motivated to join the defence forces. After passing 5th Grade, I joined Rashtriya Military School Bangalore where I completed my schooling. Being in RMS and growing up there, I got more and more determined to join the defence forces. I appeared for my NDA exam when I was in 12th and cleared it but, unfortunately, got screened out from SSB. After a few unsuccessful attempts at clearing my SSB, I decided to complete my graduation and apply for the CDS.
