well....there are a few reasons which i feel has contributed to this pattern of the counselling :
1.abolishing the state quota in the NITs.
2.improvement in the level of placements(on par with many nits and above a few)
3.very good quality hostel life.
4.very less ragging(the director has gone very strict over this from 2006 and the situation has been improving day by day)
5.reasonable fee(considering all the facilities provided along with the basic needs)
6.a very good brand perception of the university (very well recognised abroad) although mainly due to the kmc manipal.
7.many still not trusting the quality and future of the new iits and bits hyderabad(to the extent they should)
