Hi Vishal,

A candidate must score above 90% in DU JAT  to be competing with other candidates to admit themselves in a good college through DU JAT under DU. According to your scores, the result is quite difficult to obtain a seat in a good college under DU through your DU JAT score. Also your best of four percentage is also less, hennce makes your possibility even less. 

Be confident and do not loose hope and try your chances of obtaining a seat in other colleges.

You can also prepare well and appear for DU JAT  next year.
