JEE

I think you should probably go for private universities like Amity University, Modi University, Manipal University and LPU. These universities have good placements.

The best government colleges for architecture are JJ College of Architecture, Chandigarh College of Architecture, School of Planning and Architecture-New Delhi and Department of Architecture and Planning-Roorkee.
All these colleges altogether do not have more than 250 seats within them. So, you are not likely to get into any of them. Though, you can get into other good colleges such as RV College of Engineering or Manipal University or Modi University.

Chandigarh College of Architecture is among the top 4 in India. Due to high competition and less number of seats, one needs atleast more than 210 marks to get into it for general.

Yes, according to your marks combined with your category, you'll definitely get into VNIT. Moreover, I would suggest you to go for better NITs as there are higher possibilities for them too.

Kindly elaborate your question.

The colleges are LPU, Amity, Manipal (in top 10 for architecture), SRM, BMS College of Engineering, R V College of Architecture, Lingaya's University and Modi University.

Yes, you can surely get CSE but the colleges may not be good. I would suggest you to apply in SRM or VIT by giving their exams.
