Sorry for the late reply.

Hello Abhishek,
VIT, Vellore is one of the most prestigious private college of India. Top class faculties and top class education with quality students is provided to its students. Many companies go for placements at Vellore with different scale of pay. The highest package offered in VIT this year was 16 LPA by LinkedIn. Many other companies like Flipkart, EBay, Deshaw, Cisco, InMobi and McKinsey offered package of more than 10 lacs and average salary is just about 3-4 LPA.

Don't expect high salary package from this branch. SPA-Delhi is one of the finest institutes for B.Arch.

You need to score a minimum of 140 marks.

Yes, you can get admission through MHT-CET in Maharashtra state colleges.

First, I would like you to be more positive. Why expect less than 50%? JEE Mains can give you admission in NITs or CFTIs and it is basically for IITs. Ranking depends to a great extent on your performance in the exam and to a limited extent on the scores of other students. Better the rank, better the institute you will get.
