Hello

According to your percentile and based on the previous year's cutoff, chances are less to get seat in NITs, IIITs through JoSAA Counselling.
You have decent chances to get admission through state level counselling.

You can get a seat through Punjab state counselling in the following colleges:

IK Gujral Punjab Technical University Campus, Mohali- CSE
Chandigarh Engineering College, Landran Campus, Mohali- CSE
Beant College of Engineering and Technology, Gurdaspur- CSE
Amritsar College of Engineering and Technology, Amritsar
