Hello,

You cannot get admission in B.Arch in Indian Institute of Technology as it does not accept NATA score. The admission to B.Arch in IITs is based on merit in JEE Advanced and Architecture Aptitude Test (AAT). You must qualify in JEE Main Paper 2A to appear for JEE Advanced and then you need to appear for AAT. There is no provision to apply for B.Arch with NATA score. Here is the link where you can find the list of institutes accepting NATA score

You have to apply for those institutes separately for admission to B.Arch.
