Hello,

The University of Delhi, informally known as Delhi University, is a collegiate public central university, located in New Delhi, India. To fill the DU application form 2020, aspiring candidates can visit the official website du.ac.in and click on the UG admission portal 2020 tab.

For admissions in DU for courses like Bsc zoology or BSc microbiology the percentage of any 4 subjects should clear the cutoff of the college you are interested in (however if subjects like physical education are taken under best four around 2% is deducted from the total best 4  percentage).
So yes you are eligible for all the DU colleges providing Bsc zoology and Bsc micrology courses.
Hope this helps
