NATA

Very tough chances for you to score a seat in NIT or IIITs being a general category student. So you may have to shift to other colleges.

Hi,
You would need a NATA score of 100-120 or JEE paper 2 score of 160-180/390 with a decent class 12th score to get admission in JU.
According to last year cut off,
2013: 1784-5489
2014: 861-4767
They also take admission on the basis of WBJEE rank.

I think you cannot get admission in current session. For admission, the current session result will considered and as per rules candidate must have passed 12th with PCM with 50% of aggregate marks and 50% aggregate overall marks. However, you can apply for next NATA, scheduled to be held in July-2019.

The worst university for architecture, especially because of its poor classwork and professors like Anil Bharti, Rakesh Arya, Rakesh Ranjan, Admit Kumar, Vishnu Mathur, Chitkabra Rahul Kukreti, etc. Never even think about it.

Yes, there will be exam centre in Pune. Details regarding which will be mention on you admit card.

For Bachelor in Architecture, top entrance exams is given below:
NATA
JEE Main and Advanced
AMU Arch
KIITEE
IPUCET
COMEDK UGET

Marking and ranking is not, but the final admission will be affected as there is SC/ST quota. If you belong to general category, then I don't think it will be a problem.
