Best of luck.

Yes, you are eligible and you can apply for the same.
It lies between 55 to 70% for SC/ST/OBC candidates
The cut offs change every year. They're a bit different for different categories (general, OBC, etc.). And for students coming from various boards (state, CBSE). You can get previous year cutoffs and merit list on the Internet. The college website has all the information regarding registration, admissions for FY, which has started, I suppose.

Hope this helps.

Why not, sure you can pursue but mathematics is compulsory. There is basic mathematics in CS that's don't worry about mathematics. Let it happen.

There are chances, of course. I suggest you to contact the university yourself and be more clear regarding the situation. Good Luck.

Yes, you can apply for NEET. But physics is an important subject in NEET, so focus on that. All the best.

This rank is enough for your admission in government colleges. You are eligible for getting a merit seat in government engineering colleges.

One of my friends is in jet airways and she also passed out from frankinn I believe.

Hello,
Hope you are doing well. No, you are not allowed to get NITs with 152 marks and 64.8% in CBSE because you are from general category and your marks do not satisfy NITs cut-off offered for general category. You can try for some other colleges which accept JEE Mains paper 2 score and ranks.
NITs won't be possible for you.
All the best.

Please indicate your state of domicile.

Since admissions in engineering/medical colleges on an all India basis are based on central open tests which are based on CBSE syllabus so it's better to study CBSE after 10th.
