Vellore

If you are seeking admission in electrical engineering branch then my suggestion would be VIT. It is one of the most reputed private colleges after BITS-Pilani. It is the best option in every context whether it is the environment, placement, fest, exposure or anything else. It is better than BMS-Bangalore. BMS-Bangalore is also a good option. Now, it's up to you, but first of all, you have to clear its entrance exam.
Good luck.

I'll prefer you to opt for the VIT as this college is far better than the Thapar University as VIT is one of the top private college of India and also this college is better than Thapar in every respect whether it is placements, faculty or infrastructure.

To get a good branch, you have to get your rank under 5k (CSE).
And, for other branches under 15k would be sufficient.

JEE Mains is not considered in here. You' have a different test to give. There is a cutoff for that, if you pass, you'll get in.

I could not understand your query, please come again. We all can help you out.

There is no category wise reservation in VITEEE exam, everybody is considered same. Regarding preparation for CSE, you need only 2 things:
I) Good grip over NCERT textbooks and previous years VITEEE question papers. ii) Proper time management, as the questions are not tough. But, you need to solve as much as you can to get a good rank.

Yes, you can easily get admission in this college at this score and also in the CSE branch in the first round of the counselling.

See if you want scholarship from the college side only then you must be in the top 3 students of the college but if you can't achieve it then you can apply for private scholarships other then the college. From that, you can only pay off your college dues.

For that in the non-core branches, you have to secure under 50k rank and if you want to take admission in core branches then you have to secure under 10k rank. For CSE, you have to score under 1k and for ECE under 5k rank.

For that, you have to score under 30K rank to get into this college's main campus that is of Vellore and in the non-core branches but if you want admission in core branches then you have to score under 10k rank.
