Dear Student,

Yes, you are eligible to fill the form of NDA even if you belongs to commerce background but you have to seperately clear the NDA-1 exam which is totally based on the Basic Mathematics from class-8 to class-12. Clearing condition is you have to score atleast 30% of the total marks in the Mathematics exams which is almost 90 out of 300.

And last if you did not have Mathematics subject along with commerce then you are only eligible to go for Army entry only. For Navy Entry and Air force entry it is compulsory that you must have 12 or equivalent passing certificate in mathematics subject.

Hope this information helps you.

In case of any doubts you can comment me

Thank you and good luck.
