I am in my second year of graduation(bsc mathematics) , I am a girl and I really want to join Indian navy and I do want to know the exams which I should take
You need to give the NDA or NA entrance exam. It is conducted by UPSC two times in each year. You'll have to given this written exam which will be followed by a interview panel of SSB and medical tests to check your fitness by the Indian . Your physical as well as mental fitness everything is tested in detail.
Best wishes. Thank you.
