Hi, i'm sorry to inform you that DU doesn't offer BCA course. Although it offers similar course  to BCA - as B.Sc (hons) in computer science. Athough the syllabus is somewhat similar, B.Sc course includes more of theoretical knowledge than practical. BCA is a more balanced course which includes both Practical and Theory and some colleges also peovide a chance to perform minor projects while studying the course.

For the B.Sc course in DU, you will have to appear for an entrance exam and cutoffs for this course are generally high.

Good luck
