Hi Priyanshu,

To get a vague idea on admissions into architecture colleges, your NATA cutoff is required. NATA cutoff is different from NATA score. The calculation of NATA marks is done by adding the 12th board or HSC percentage (outof 100) with the half of NATA score. Here, marks obtained in individual subjects is not considered. It is just necessary for you to have a pass mark. 

If your cutoff is above 100/200, then you might get a seat in a very decent college.

You can either apply directly for private universities or go for state counselling. 

All The Best
