Hi Ishika,

Considering the rank you have been placed in with the last year cut off rank in collegesunder DU through DU JAT , Your possibility  of  obtaining an admission in colleges under DU is quite difficult.

  Therefore if you are assured to do your graduation in DU you can prepare well and appear next year, score high marks and have your seat in top college under Du through dujat.

or you can also start applying for  other colleges with your hsc mark

Hope this helps

All the best
