Architecture Entrance Exam

Hi,
Please be more specific about this. Then only, I will help you out more. Thank you.

Yes, you can get admission in NITs.

Hello, hope you are doing well.
No, there are no chances that you will get a government college because for government colleges, you need to score 100+ marks in NATA.
You can go for top private colleges. Also, you can try for CEPT University, MS University, DY Patil College, Nirma University, etc.
All the best.

Hello, hope you are doing well.
Yes, definitely, you are eligible to get NIT on the basis of OBC NCL ranking because with CRL ranking, it may not be possible to get an NIT. You should try for MANIT Bhopal, NIT Warangal, NIT Calicut, etc.
Also, you have a chance to opt for IITs also. Find the best one and go for counselling.
All the best.

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.

Without being able to qualify in any of the above exams, you won't get admission in the colleges which offer admission on the basis of these two exams, including IGDTUW. I would suggest you go for private universities which have their own entrances.

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.
