Doon Business School is a great option for integrated BBA+MBA. It is ranked by India Today as the 5th best BBA college in North India and the 24th best in India. Students receive not only a degree from a government university, but also a variety of career-oriented value-added certificates such as SAP-University Alliance Orientation, Big Data Analytics, Bank PO/ MBA Entrance Training, Tally 9.0 ERP, NISM on Stock Market/ Mutual Funds, Entrepreneurship Incubation, Web Designing, and so on.
DBS's location is favorable for life projects because it is close to green industries such as Samsung, Videocon, and Rasna.
My brother is a DBS student, so I can assure you that the college will invest far more in the students' overall development than any other institute. It'll be a place full of fun as well as endless opportunities and learning.
