Hello Kiran,

Yes,you are eligible to write NDA(National Defence Academy) Exam,But you will 

be only considered for the Army wing only,you will be not considered for the 

Indian Airforce and Naval because for these you should have passed 10+2 

with Mathematics and Physics as compulsory subject.

Thank You.

Hope it was Helpful. 

Dear Candidate,

The paper pattern consists of Mathematics (300 marks), GAT English (200 marks), GAT General Awareness (400 marks). You can appear for Army Wing of NDA. But apart from educational qualifications there a other physical qualification criterias too. Here is a link for you to consider:
