Hi,

If I score 240+ in JEE Main paper 2 (B.Arch.), you will definitely get an NIT. Actually, this score is good enough to get you a seat in SPA (School of Planning and Architecture), Delhi. To study B.Arch. in top NITs and SPAs, you need a rank below 3,000 which you can easily get if you score above 240 in paper 2 of JEE Main.

Hope this helps.

Cheers!
