Hi,
I think with this score, you have an average chance to get admission in SPA-Delhi. For an OBC candidate, 280+ is considered good for admissions into B.Arch course of SPA Delhi. The cutoff of JEE Main paper 2 is not released in the form of score/marks. Rather it releases in the form of opening and closing ranks.
