Will Male-Female ratio ever change in IIT's?

I cannot agree with Rahul nor Rajat.

MIT is the top school in the world for engineering.  It has an extremely rigorous curriculum, and is very selective. It nearly has a 1:1 ratio of males to females. However the ratio of male applicants to female applicants is 3:1.  This shows that the females who applied were much more highly qualified (and there is no affirmative action towards women).  So your thought that "I don't think they had it in them to go through the rigorous process of IIT " is erroneous- if females are more qualified in America in the engineering field and such a ratio can reach in the top college, then it can definitely be true in India too.

The difference is society.  In america, females do not face as much sexism as they would in India, and are encouraged to go into fields with technology.  They do not think of themselves as any less intellectually- because they aren't.  Intellectual achievement and gender are mutually exclusive.  Success has everything to do with hard work and self confidence.  Problem is, in India, women are lacking the latter because they constantly hear people say things lake Rahul "they don't have it in them".  Society molds a person into who they are.  Women are just as capable intellectually as men.  It is not the standards for women or their intellectual-ability that has to change.  

It is the societal view and attitude towards women that has to change.
