Hello Sukhdev,

As per my knowledge , if You are Interested To get Admission In BCA in DU , then I think You are Not Eligible, Because Maths Is Compulsory In Your 12th Exams. But, If You are Interested To get Admission In BBA, then You are Eligible But you will get Admission In DU only when If You Scored More than 70% Marks In your 12th exam.

Hope It Helps
All The Best !!
