Hii Aspirant, You had not mentioned for which stream you want to apply in DU.Your marks in 12th are not too much to get admission in DU university by the general rank. For BA you got to score atleast 82–83 % for an average college and above 90% for a north campus college. Cut off for B.com (hon) and Eco (hon) are high . The least cutoff for B.com(h) for even the not so good colleges of DU is 92–93 %.

If your percentage was 80+℅ then there will be chance but dont loose hope wait for last merit list. I am providing you a link through which you can check last year cutoff percentage.
