Hello.

There are many colleges across the country which accept NATA score for admission. Here i'll list a few colleges which is known for its excellent academics in Architecture:

School of Planning and Architecture (Delhi);

Sinhgad College of Architecture (Pune);

Rizvi College of Architecture (Mumbai);

Dept. of Architecture, NIT Calicut;

Dept. of Architecture, NIT Tiruchirapalli;

R V School of Architecture (Bangalore);

Chandigarh College of Architecture (Chandigarh);

Dept. of Architecture, IIT Roorkee;

Dept. of Architecture, BIT Mesra (Jharkhand);

J J College of Architecture (Mumbai).

If you want admission in any of the reputed government institutes, you have to score 150 or more. The cutoff are not that high. But to be on the safer side, 150+ is a good score.

If you don't get admission in any government institute, and want to join a private college, a score anywhere between 90 and 130 is good.

Also, class 12 marks are very important for admission. A minimum of 50% aggregate is required for you to be eligible for admissions. 

All the best!
