B.Tech Computer Science and Engineering

Hi,
With 54% marks, you won't get any good college. First of all you apply for a reappear and if your aim is only getting B.Tech degree you can take admission in Chandigarh University. Last year they were selling seats of B.Tech for Rs.10000. Even the IT companies demand for at least 60% marks in class 12th. All the best for your future.

Total fees of B.E in Computer Science and Engineering in Bhilai Institute of Technology, Chhattisgarh is INR 2.80 Lacs. For more details you can visit : https://www.shiksha.com/b-tech/course/b-e-in-computer-science-and-engineering-bhilai-institute-of-technology-chhattisgarh-other-201837.

Yes, what you have heard about the placements of Thapar University is true, the college placements as of now is not as worthy as it is in last 4 years, and this is due to lack of good teachers.

Yes, you can get admission in Indo Global campus near Chandigarh on the basis of Diploma in ECE or any other stream.

Your son has to clear JEE Advanced for getting into any of the IITs in the country. He has done well in JEE Mains. I think he is eligible to apply for JEE Advanced. Through JEE Mains, one can only get NITs, IIITs and other colleges, but not IIT.

Percentile is only an indicator; the game lies on ranks. However, if your son is a 'home' candidate there yes. There is a higher chance of getting CSE. But if he is an 'other state' candidate then a bit of tough. But my opinion is only suggestive.

From BMSCE Bangalore, SVUCE Tirupati, and GNDU Amritsar for B.Tech in CSE department, I'll prefer you to opt for the BMSCE Bangalore as this is the best college all in terms of placements, infra and faculty.
