All three are completely different. BBA is recommended, if you want to enter management. MBA would be needed after BBA. So, if you are planning to pursue MBA then go for BBA. BCA is Bachelors of Computer Applications. If you are interested in making a career in IT, then go for BCA, B.Sc can be done in IT, Computer Science, Physics, Chemistry, Maths, Biology, etc. If you want to make a career in IT, you can do B.Sc IT or B.Sc CS. I would personally not recommend you to do B.Sc in plain sciences unless you want to become a teacher or scientist. Ask yourself what do you want to do in life? What are your aspirations? Make a decision on the basis of your interests and aspirations. All the best.
