What is the Exam?
The Combined Defence Services (CDS) examination, conducted by the Union Public Service Commission (UPSC), is a prestigious national-level competitive exam. It serves as the gateway for commissioning officers into the Indian Armed Forces, including the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), and Officers Training Academy (OTA). As exam strategists at Exam Bhai, we emphasize that the CDS is not merely an academic test; it is a personality and aptitude assessment designed to select candidates who possess the intellectual rigor and discipline required for a commissioned officer's role.
