Hey riya,

Last year, the cut off rank for the OBC category students, for admissions in the B.com(h) was 697. With your OBC rank of  839, you can be hopeful of getting admission, as the cut offs change every year. Difference of 100-200 ranks in the cut offs in the simultaneous years is quite normal, so hope for the best. Hope this helps, thank you for asking question here at careers360.
