Is Chandigarh University just a name for B.Tech CS or it is really a good college? How is it compared to Thapar and PEC?

Honestly, for BTech CSE I'd pick Thapar. It has a stronger engineering reputation, better placement opportunities and a stronger peer group overall. Chitkara is decent too, but if you have both options, I'd go with Thapar.

If you have CSE at both, I'd pick Thapar. Chitkara is a decent option, especially if fees are a big factor, but Thapar has the stronger engineering reputation and overall peer group. If the fee difference isn't a major issue for you, I'd go with Thapar.

Yes, Thapar has international recognition. It is ranked in global rankings like QS and THE, and its eligible engineering programmes also have ABET accreditation. So for higher studies or opportunities abroad, Thapar is a recognised name.

Yes, Thapar is a good option for BTech. Academics, placements, faculty and campus exposure are all pretty good. Especially for CSE, COE, ECE and ENC, there are good opportunities. If you're getting your preferred branch, I'd definitely consider it.

Thapar has pretty solid BTech placements, especially for CSE, COE and related branches. A lot depends on your branch and skills, but overall the placement scene is one of the better things about Thapar.
