Hello there. Hope you are doing good. I would like to tell you that DTU has started offering BBA course since few years only. Generally, as per previous cutoff trends, 90 percent and above is a good percentage to get admission into DTU. However, your percentage is close to 90 so there are decent chances of converting DTU. Moreover, since you belong to Delhi, preference will also be given as DTU is a state governed university.

I hope you found this answer helpful. Good luck for your future.
