Hello Dear,

It is very difficult to predict the college but according to you,  you got 91.7% in class 12. You do not mention your category. So I am assuming that you belong to general category. There is minimum chance to get admission to Delhi University for B.Sc  chemistry. Because according to the previous year, the  cutoff of B.Sc (Hons.) chemistry for general category  in different colleges of Delhi University such as

Shri Guru Tegh Bahadur Khalsa College  95-97,

Miranda House 96-98,

Zakir Husain Delhi College 96+,etc.
