JEE Mains paper 2

You can get admission in this campus. This is a private self-financing college and the seats are usually available. This score is enough for admission to this campus.

Yes, you are eligible.

Yes, you can get admission in NITs.

Last year (2017), my friend got 219 marks in JEE Mains Paper 2 and 81% in 12th from CBSE Board and he belongs to OBC category. His Gen rank was 9243 and OBC rank was 3800, still, he didn't get any college. So, I think for a general candidate, the score must be above than 250 if Board marks are not included.
All the best.

Hello, hope you are doing well. You have 113 marks in NATA, so most probably you are eligible to get government colleges of your state. Also, you can try for CEPT University, MS University, Nirma University, etc. which will offer you a good environment as well as you will easily get admission in these colleges.
All the best.

Hello, hope you are doing well.
No, sorry, with JEE paper 2, you only get the architecture colleges of India for B.Arch. But for B.Tech, you need to get good marks in JEE paper 1 to get admission in Symbiosis College. Computer science will be hard to get with average marks. It requires good marks in JEE for best colleges.
All the best.

You need at least (being from general) 75% for admissions into NITs. Though you have an excellent score, still you won't be able to get into NITs. Try for options which have the same reputation and lower boards score criteria.

Since, you have less marks in Mains, I would suggest you to get into private universities with their own private entrance such as Manipal University (comes in top 20). Other such recommendations are LPU, AMITY, SRM, VIT, etc.

Hello,
I hope you are doing well. No, you are not eligible for NIT with 147 marks in JEE Paper 2. Go for government colleges or some private college like DY Patil College, Nirma University, IPS Indore, MS University. You will definitely get colleges with these marks but you are not eligible for NITs.
