Hello student ,

Yes, NATA entrance exam  is enough for a seat in karnatka . But you should know that the merit will be based on your aggregate marks i.e including your NATA as well as intermediate marks too.

On the other hand  If Karnataka is your home state then you can surely have a finest government architecture college and private colleges out of as well as in Karnataka itself by going through this exam. 

Hope it helps. 

Thank you :)
