What is the Exam?
The Combined Defence Services (CDS) examination is one of the most prestigious competitive exams in India, conducted biannually by the Union Public Service Commission (UPSC). It serves as the gateway for commissioning into the Indian Armed Forces as officers. While the Indian Military Academy (IMA), Indian Naval Academy (INA), and Air Force Academy (AFA) are exclusively for male candidates, the Officers' Training Academy (OTA) offers a path for both male and female candidates to serve as Short Service Commission (SSC) officers in the Indian Army.
For female aspirants looking to serve the nation, the OTA route is the primary entry point. The selection process involves a rigorous written examination followed by a five-day personality test, known as the Services Selection Board (SSB) interview, and a comprehensive medical examination.
