What is the Exam?
The Combined Defence Services (CDS) examination is a prestigious national-level competitive exam conducted by the Union Public Service Commission (UPSC). It serves as the gateway for commissioning into 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 General Knowledge (GK) paper is often the deciding factor for candidates, as it requires broad awareness rather than rote memorization.
