See in most of the cases, the BBA courses explanation are done in classes in both hindi & english (the technical terms in english & explanation in Hindi). Although, there can be colleges where the education is carried out in English only (for that contact the helpdesk of that college). Apart from this the books and materials from which you will study will be in english & in most of the cases, you have to give the examination in english only (As there are less hindi books, how will you get the technical terms in hindi).
