Hello Aspirant,

See Combined Defense Services Examination is conducted by Union Public Service Commission (UPSC) every year for admission of aspirants to the courses like Officers Training Academy, Indian Naval Academy, Indian Military Academy and Air Force Academy. As you have mentioned that you are a student of B.Sc Agriculture so the eligibility criteria of CDSE prescribed by UPSC says that you are eligible for CDSE only for courses like Officers Training Academy and Indian Military Academy if you clear CDSE exam but you are not eligible for Indian Naval Academy and Air Force Academy because it requires Engineering Degree which you don't have.

Apart from above educational qualification criteria there are some other criteria which one should satisfy in order to apply for CDSE like the age of the candidate must be 20 to 24 years and the nationality of candidate should be any one of the following :-
