Students seeking admission to B.Sc. should have obtained an aggregate of 60% marks in the subjects concerned, i.e., Physical Science, Biological Science, and Mathematics.

Since you have chosen BBA after BBA the natural progression is for doing an MBA which is apt and right. Opting for a job after BBA will not give you good salary, good job profile, low end work and it will be of uncertain nature. Therefore I would not recommend you to join employment immediately after BBA. Today doing a good post graduation is important. India has one of the largest student populations in the world. Therefore, education is always a hot topic in the country. Currently, the BBA degree is gaining momentum amongst students. There was a time when only a few private colleges and institutes were offering this degree, but now, almost every major university in India is offering BBA. Therefore, it has become even more accessible. Companies also actively look for BBA graduates and offer them a good salary and benefits. Best Universities are:
ITER Bhubaneswar, Bhubaneswar.
Geeta University, Panipat
MSRIT Bangalore - Ramaiah Institute of Technology.
SRM
VIT
BITS Pilani
Amity University.

Both have their own advantages. I think you must go for BCA because in it you can explore more things rather than just focusing on AI and ML. B.Sc. in AI and ML
The programme will help candidates:
To understand, evaluate and analyze the history of Artificial Intelligence. To identify those areas of the domain which are yet to be explored. To apply basic principles of AI in solutions that require problem-solving, inference, perception, knowledge representation, and learning. To become proficient in developing applications in an 'AI language', expert system shell, or data mining tool. To gain the ability to explore the current scope and limitations, and societal implications of the domain. BCA full form Bachelor of Computer Application is a 3-year undergraduate course that imparts knowledge on the basics of computer application and software development. BCA subjects include database management systems, software engineering, operating systems, web technology, and computer languages such as HTML, C, C+, and Java.
