Hello Ashish...I would suggest you to choose your career according to your aim and goal in life. If you are hard-working then a sparking future is waiting for you.Among BA, B.Sc And BBA , B.Sc is right choice, because many Job demands for particularly Science Graduates. Pursuing your degree from Correspondence is not at all an issue institutes like IGNOU and SOL (Delhi) etc holds equal value as regular mode.

 It would be beneficial for you, if you go for B.Sc in specialisation courses like B.Sc Radiology, B.Sc Anesthesia Technology, B.Sc Agriculture, B.Sc Nutrition Science and Food Technology, B.Sc Multimedia, B.Sc Fisheries, B.Sc Aviation, B.Sc Genetics, B.Sc Information Technology etc.

Hope your query is resolved.

Good Luck

Hi aspirant,
There is nothing better or worse when it comes to the three courses. It all depends on your interests. Since you are interested in BBA and B.Sc. computer science you should choose to do one of them.
Computer science is a in-demand field and a B.Sc in the same will be good, it will deal more of the theoretical and research part rather than the application. If you are interested in research and computer science you should choose B.Sc computer science.
BBA will teach you about business and administration. If you wish to choose a career in Business then choose BBA. BBA also has better employment opportunities than B.Sc.
As you mentioned, you will be doing a job and study part time, so in my opinion you should choose BBA as it easier to study part time than the other and also has better employment opportunities.
The rest depends you and your interest.
Hope this helps.
