NATA

I am sorry to say, but your marks are not enough to get admission in B.Arch in IPU.
Colleges consider 90+ marks in NATA for admission in B.Arch.
Also, there is no guarantee of getting admission by having 90+
I hope, you understand my point.

No, you cannot do architecture, if you are from commerce stream. From 2018 on-wards, only science (PCM or PCMB) students who have scored at least 50% marks in class 12th with mathematics, as compulsory subject will be considered eligible to appear in architecture entrance exams.
Before 2018, commerce with maths students who have secured at least 50% marks in class 12th are eligible to appear in architecture entrance exams like NATA, JEE Mains paper 2 etc.

Considering your JEE Mains paper 2 and NATA score there is no way to get admission in USAP. I know you have OBC quota but your rank is too high.

R V School of Architecture, RVCE, Bangalore
Faculty of Architecture, Manipal University
Sinhgad College of Architecture
Rizvi College of Architecture (RCA) Chitkara
School of Planning & Architecture

They even consider 70 marks in NATA for Anna University counselling and I'm sure about it.

Sorry, but your rank is too high with 250 marks in JEE Mains paper 2.
300+ marks are considered for admission in B.Arch for NITs,There is no chance for NIT/IIIT or any government college.
So, you should try for any private college/university.

You may get admission in an architecture college with this score as a score of 90+ is considered in NATA to get admission in B.Arch in various Govt. colleges. There will be a plenty of colleges available for the same, attend NATA counselling. Best of luck!
