BBA

It depends on your career aspirations. As far as simple academics is concerned, there are two ways you can go about studying Psychology:
1. Go for a regular Bachelors program from a reputed University following it up with Masters & then M.Phil. and/or Ph.D. (needed only if you want to go in teaching and research).
2. Study the basics from 11th & 12th Standard NCERT books, which are really good and go for a Open University or Distance Learning Masters program after completing your BBA.
A three year Bachelor's degree in any field is required to pursue a Masters course from IGNOU and most other distance learning programs. The curriculum is really good and most courses have contact programs and practicals.
You have an option of various specialisations during Masters - Clinical, Counselings and Organisational Psychology. You may choose depending on your future career aspirations.
