Claim Free Beta AccessThe educational qualification for IMA, INA, and AFA through the CDS 2027 exam requires a Bachelor's degree in any discipline for the Indian Military Academy (IMA), an Engineering degree (B.E./B.Tech) for the Indian Naval Academy (INA), and a graduation degree with Physics and Mathematics at the 10+2 level or a Bachelor of Engineering for the Air Force Academy (AFA).
What is the Exam?
We at Exam Bhai recognize that the Combined Defence Services (CDS) examination, conducted twice annually by the Union Public Service Commission (UPSC), is one of the most prestigious gateways into the Indian Armed Forces. For aspirants targeting the CDS 2027 cycle, understanding the nuances of selection is vital. The exam recruits elite officer cadets for four premier training institutions: the Indian Military Academy (IMA) in Dehradun, the Indian Naval Academy (INA) in Ezhimala, the Air Force Academy (AFA) in Dundigal, and the Officers' Training Academy (OTA) in Chennai.
Clearing this examination demands a rigorous multi-stage evaluation consisting of a written test administered by UPSC followed by the formidable five-day Services Selection Board (SSB) interview. Because each academy serves a distinct branch of the military, the criteria governing who can apply—especially regarding academic backgrounds—vary significantly across the board.
