Disclaimer: This is my personal view and please do not take it as a public/ general point of view.
UPES is an institute that is known for courses offered in petroleum and energy course for engineers. For BBA it is still relatively a unknown institute. One of my cousins had an experience where she was called for the interview and there was no dress code! Also when the faculty were asked question in the Q and A round, the response was not up to mark and answers that they were giving were evasive. So my suggestion would be not to opt for UPES for BBA.
