Tnx for rply,As per my info. these seats (reserved for females) are not at the stake of male candidates, i.e. it wont decrease the no of seats for males, this much no of seats will increase and will not be alloted from current seats. So i dont think it will affect much. What do u think??

You are partially correct. Actually if you see the number of seats added this year for girls is around 700-800,but considering currently total number of seats in IITs is around 10.5 thousands so the number of seats to be reserved for girls should be around 1400-1500 , considering 14% reservation for girls but in realty only around 700 supplimentary seats sre added so the remaining quota for seats of girls is filled by the tqking certain number of seats from open quota. So the girls reservation seats are not supernumeray in reality.

Tnx for rply,I m talking abt NIT not IIT, wat is the situation of it?

Cut off NIT will fepend on cut off of IIT dude.
Students first preference is always IIT then they look for NITs.
