Nirmala, AIMS has good placement opportunities for BBA students than HITS Chennai. As HITS Chennai offers good placement opportunities to B. Tech students than any other branch. But International School of Hospital Management (ISHM, Kolkata) will have its first BBA batch completion in 2023 as its first batch for BBA in aviation management started in 2021. So, nothing can be said about the placement opportunities for BBA students.

Hope it helps to clear your dilemma, thankyou!
