BCA is a very hot course in coming years.

But I'm very to inform you that BCA course is not provided by the college you mentioned. There are many other courses you can refer to at https://www.jmc.ac.in/academics/ugcourses

Jesus and Mary College being part of DU does not conduct entrance exams. And there no BCA course provided by any DU college. It provides B.Sc(H)CS. The admission to this course is strictly through your 12th marks.

BCA is more of a professional and practical course whereas Bsc will provide you both theoretical and Practical knowledge. But if you strictly want to pursue BCA there are other reputed colleges than DU in IP

All the best
