Hello,

The Council of Architecture (COA), which is the exam conducting body, doesn’t conduct counselling of NATA. Instead, candidates have to apply in the desired institute among the participating institutes separately based on their NATA scores for admission to B.Arch course. To be eligible for participation in NATA 2019 counselling, candidates have to score the minimum cutoff marks in the two individual components and also in aggregate. Additionally, the NATA applicant would also have to meet all the other eligibility criteria specific to the institute. Again, since there is no centralized counselling of NATA 2019, there is no uniformity in the counselling processes adopted by these institutes.
