Even I want a seat in CSE there but I believe that JNGEC doesn't offer CSE. I checked there website and there were only four courses :

• Electronics & Communication Engineering (ECE) (60+3* Seats)

• Civil Engineering (CE) (60+3* Seats)

• Mechanical Engineering (ME) (60+3* Seats)

• Textile Engineering (TE) (60+3* Seats)

You may get seat , kindly attend counselling , there are also other government colleges which  have CS .Good Luck.
