1.why in21st century their no change mentality of people? 2.why girl s not aloud give direct nda exam after 12th??

Hello,

Here is answer to your doubts :

1. Yes, indeed the mentality of most of the people in our society(india) has still not upgraded and that's simply because the old generation people are rigid in their thoughts and they believe in what they were taught when they were growing up and hence they judge others on basis of what they learnt when they were growing up.Theirs thought are little conservative as well as narrow minded.
For a change to take place,it requires lot of decades and people in our society will also change with time.
In past,200 years ago there were a practice called SATI, in which a widow sacrifices herself by sitting atop her deceased husband's funeralpyre .
Then Raja ramohan roy came and abolished this practice with the help of Britishers.
So, in coming years we will definitely see a change in mentality of people.


2. Candidates of age 16-19 can apply for NDA, but most girls of that age (16-19) are not physically strong that's why NDA prefers Male candidates.
But if you are interested in joining Defence Services, then, you can apply for CDS OTA (Officer's Training Academy) examination and by qualifying the examination, you can join in the Indian Defence Services.

Good Luck
