Hi Animesh,

Heartly congratulations to you for securing that amazing rank.This came as a big shocker to me as well. Surprised!  Check these details I could get some data for you from the official sites. For CS branch the cut-off is around 850 to 900(in 2nd round which is the final round). I would provide details of ECE as well. 

For EC it is about 1500(2nd round). There is a lot of stiff competition this year in bagging CSE. I would never advise you giving college a higher priority over branch so,all I can say is keep your fingers crossed orelse,you can even check the south campus as well. Keep yourself highly updated with the cutoffs everyday. Best wishes!
