Only unmarried male candidates are eligible to appear for the NDA entrance exam 2019.The minimum age limit is 16.5 years and the maximum limit is 19.5 years.Girls are not allowed to attend the exam as per the the details given in the eligiblity criteria.However a proposal has been made to make this possible soon for girl candidates.
Hope this helps.
Girls are not eligible for giving NDA exams. NDA or NA is the entrance exam conducted by UPSC twice a year to recruit male candidates in Indian Army, Indian air forces, and Indian Navy. So, girls are not eligible yet now. BUT very soon news is coming that girls would get appointed too but till now such headlines are not coming officially. Hope you find it useful.
