About Defence Exam

Competitive exams for defence are conducted by the Union Public Service Commission (UPSC) and other defence authorities for recruitment to various departments of the Indian Armed Forces. 

Candidates are tested on their aptitude in general knowledge, reasoning, English, and mathematics. Besides these, candidates are also evaluated on their physical fitness level. 

Entering the armed forces is fiercely competitive and challenging. But the right resources and guidance are the means to fulfilling your dreams of getting into the armed forces. 

Different Types of Defence Exam

Some of the most prestigious defence exams are National Defence Academy (NDA), Chief of Defence Staff of Indian Armed Forces (CDS), Air Force Common Admission Test (AFCAT), Central Industrial Security Force (CISF), Intelligence Bureau (IB), among others.
