Its good that you scored 97 in NATA. But telling you simply that which college will offer you admission is quite difficult, as you have not mentioned the state to which you belong.

Moreover the colleges which offers admission to the B.Arch Course publish their merit list or application procedure usually in the month of June/July every year either in leading newspapers or their official website. Remain in touch with the official websites or individual college websites. :)

Best of Luck!!
