hi
sorry friend girls can join after completing their graduation or if they are in final year can try for the entry
NDA (national defense academy),only unmarried male are required as per the rules and regulation and in order to be a part of the defense field then one has to follow this..
THATS true NDA EXAM held twice but only men can apply for this..
girls can join defense field ,then you can give CDS EXAM(combined defense service exam)held by upsc like NDA EXAM.but differ in eligibility conditions
CDS EXAM held in the month of February and September.
age limit for CDS=19-21 years
qualification=any bachelor degree
must be mentally and physically fit and fine
unmarried male and female
must be indian
through CDS EXAM,you can be a part of either of the defense feild as per your interest=
1)indian army
2)indian navy
3)indian air force
..so friend right now you need to concentrate on studies and when you reach degree final year then you can go with CDS exam
for exam notification you can be updated from the upsc official website=www.upsc.gov.in
good luck
thank you
