Hi aspirant

The cut off of any college in Delhi University is too high for General as well as OBC candidate.

The minimum cut off for a OBC candidate is 87% for B.sc in botany at Zakir Husain Delhi College and Swami Shardhanand College.The cut off for life science is comparitively low i.e upto 85%.

You won't be able to get it.

You can try for something else from other university.

You can check the DU colleges cut off here: http://www.du.ac.in/du/uploads/Admissions/Cut-off/2018/Science_1.pdf

All the best.
