Dear Student, 

For getting admission into any NIT,  SPA or any government college or private college for B.arch listed under JOSAA one needs to appear for JEE Mains Paper 2 and clear it and the JEE mains paper 2 have already been conducted, so i suggest you to go for a private college with direct admissions or based on their own entrance or take a gap year and appear for paper 2 next year. 

Hope this might help you.
