Hello

GNA college ,Punjab is a good college to do BTech from, the faculty is good and the placements are average.

There are many specilisation avaliable in the college, if you are not sure about which field you want to chose in future then just go for core CSE since you can change the domains as you want but after selecting specilisation you should select specilisation like Cyber sec. or data science as per your interest.

Hope this helps.
