Integrated interview coaching modules
The maximum age limit for CDS examination is 24 years as on the date of examination. There is no minimum age limit specified, but candidates typically are graduates by the time they apply. Age relaxation may apply for candidates from specific categories as per UPSC guidelines.
The CDS examination is conducted twice every year by the Union Public Service Commission (UPSC). Notifications are typically released in October and June, with exams held in February and November respectively. Candidates must check the official UPSC website for exact notification dates.
Mathematics is compulsory for candidates applying to IMA, INA, and AFA (Indian Military Academy, Indian Naval Academy, and Air Force Academy). However, for OTA (Officers Training Academy) candidates, mathematics is NOT part of the syllabus. Only English and General Knowledge are tested for OTA aspirants.
After clearing the CDS written examination, selected candidates must appear for the SSB (Service Selection Board) Interview. This is a comprehensive 5-day assessment that evaluates personality, leadership qualities, decision-making ability, and suitability for defence service. SSB is mandatory for all three services and success in SSB determines final selection.
Yes, candidates who are pursuing their final year/semester of graduation can apply for CDS examination on a provisional basis. However, they must produce their graduation certificate before joining the academy. Provisional applicants must ensure they complete their degree before joining the selected academy.
