Hello Akshara. The cutoff for B.Arch course in NIT Calicut for JEE Mains paper 2 2019 exam has not been officially declared yet. It will be declared after the JEE Mains April exam is completed and merit list is released. But based on previous year's record the closing rank for B.Arch in NIT Calicut was 1141 for Home state (general) and for other states the closing rank was 1323 (general).

Hope this helps. For further queries feel free to comment down below.

Good luck!
