Hi,
With 94/200 Marks in NATA 2019 exam and 93% score in your class 12th, you have chances of securing admission in Dayananda Sagar College of Architecture, East West School of Architecture, Reva School of Architecture, KS School of Architecture and RNS School of Architecture.

I suggest you to go with NITs if your rank is less than 800, or apply for JEE Advanced paper 2 and after results if you get the same percentile you can easily get admission in IITs for B.Arch!
If not you can go with top NITs for pursuing your B.Arch!
