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). It serves as the gateway for graduates to join the Indian Armed Forces as Commissioned Officers. Whether your ambition is to serve in the Indian Military Academy (IMA), Indian Naval Academy (INA), Air Force Academy (AFA), or the Officers' Training Academy (OTA), the CDS exam remains the most respected path for defence enthusiasts.

It evaluates a candidate's aptitude, leadership potential, and awareness of the dynamic geopolitical environment.
