Hi, you can compare both the colleges in terms of quality of education, ranking/rating, course details/syllabus and other important details like faculty members, college life, placemnets(if any), ECA/sports etc.

You can compare both the colleges i.e DU for Physical sciences and IPU for BCA from the link given: https://www.careers360.com/compare-du-vs-ipu?college=49397-6500-course=77237-44952-compareresult

In order to decide which course to opt for, do check about your chances of getting admission in both the colleges for the desired course, opt for the course which matches your interest field and further career options.
