Hello dear..

might not be getting preferential branch in any of NITs even under home state quota. Since u havn't mentioned ur state, i can tell you about Delhi colleges.
You can get DTU(ENE,EP,PCT,BT) may be before spot round but definately in spot round,u might also get DTU(PIE,MAE) in spot round if things go in ur favour. You can also get NSIT(MPAE,ICE,BT) in spot round.
Since NIT delhi is a new college with lesser branches(in number), its previous year cutoff touched around 28k after spot round.

Best of luck..
