What is the Exam?
The Combined Defence Services (CDS) Examination is one of the most prestigious competitive exams conducted by the Union Public Service Commission (UPSC) in India. 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 the Officers' Training Academy (OTA).
The exam is held twice a year, and candidates who successfully clear the written examination and the subsequent Service Selection Board (SSB) interview are commissioned into their respective wings. For aspirants, the English paper is often considered the most scoring section, making quality English grammar notes an essential asset for those aiming for a high All India Rank (AIR).
