B.Arch

Sorry to say but you will not get any college of architecture with 62 marks because 70 marks is the qualifying marks. But if you tell me your class 12th boards marks, then I will be able to help you more in the field if architecture.
If you like my answer, then raise your hand by making an up vote.
All the best for your bright future.

It's good that you scored 100 in NATA. But telling you simply that which college will offer you admission is quite difficult, as you have not mentioned the state to which you belong.
Moreover, the colleges which offer admission in B.Arch course publish their merit list or application procedure usually in the month of June/July every year, either in leading newspapers or their official website. Remain in touch with the official websites or colleges individual colleges.

Hi,
I am sorry to say but you will not get B.arch in Jadavpur University as your marks are just 84. You need a score of 150+ to get B.Arch in JU.

If you haven't registered yourself for JMI then you will not be able to take admission. You have to wait for next year now.

SPA's are the best institutes for pursuing B.Arch in the country followed by NIT's and some other institutions. So, obviously SPA, Bhopal is better if you score enough to get into it.
Good luck.
