Hello Sneha,

It is very difficult to predict the college but according to you,  you got 90.75% 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.A English/Economics. Because according to the previous year, the  cutoff of B.A English/Economics for general category  in different colleges of Delhi University such as

Shri Guru Tegh Bahadur Khalsa College 95-98.50(for economics)

Shri Guru Tegh Bahadur Khalsa College 95-97.50(for english)
