Hi,

The cut-off for admission in Bsc course in Computer Science in any of the colleges under Delhi University is around 95% in the recent years so whether you will get admission in any of the DU colleges with 85.5% aggregate is not certain. Since you have OBC certificate & the results this year has created confusions for every board so you may try applying for the process & wait for the counselling process to begin.

Hope this helps.
