Since your father is serving in the Indian Army, you may be eligible for admission under defense quotas in various schools, including Army Public Schools (APS), Sainik Schools, and Kendriya Vidyalayas (KV). You should check the admission guidelines on their official websites. Prepare necessary documents like your father’s service certificate, transfer details (if applicable), birth certificate, and previous academic records. Visit the school where you seek admission and inquire about vacancies, entrance tests (if required), and application deadlines.
