What is the Exam?

The Combined Defence Services (CDS) examination is a prestigious national-level competitive exam conducted biannually by the Union Public Service Commission (UPSC). We at Exam Bhai view this as the gateway to the officer cadre in the Indian Armed Forces. The exam facilitates entry into four premier training institutions: the Indian Military Academy (IMA), the Indian Naval Academy (INA), the Air Force Academy (AFA), and the Officers' Training Academy (OTA). Success in the written exam, followed by the rigorous Services Selection Board (SSB) interview and medical fitness tests, grants candidates the opportunity to serve as commissioned officers.
