Chances are very less for you to get admission in Punjab engineering college at this rank. You should try JAC Chandigarh counselling and wait till spot round keeping the hope high and expectations low.

In my opinion, IIT-Ropar is better than IIT-Jodhpur in terms of education, atmosphere and ranking.

In my opinion, Thapar University will be the best to pursue CSE. As it is among the best private colleges in India. It's the faculty members, placement and exposure are outstanding. So, if you are getting Thapar for B.Tech in CSE, you should not leave it.

Jatin, LPU is a brand in itself. It has been ranked as one of the best universities by various agencies on the basis of its infrastructure, its placements, its pedagogy, its faculty, to mention a few.
The university leaves no stone unturned to shape the future of its students.
All the three courses are different from each other and have their own individual value. They all are equally good, so important is your interest in them. Better would be to meet the people of the concerned department and have discussion with them. After discussion, you can decide which course is meant for you.
