Kruthik you cannot do MBA right after 12th class irrespective of the stream you had in your 12th class as MBA is a Post-graduation degree. For doing MBA from any college you will need to first complete graduation which can be done in any stream and then you will need to clear MBA exams like CAT, XAT, MAT, CMAT etc. and go through the whole procedure of GD, interview to get admission in any college to pursue your MBA degree.

But right after 12th class, you can look forward to joining an integrated program of 5 years i.e. BBA (3years) +MBA (2 years). There are many separate exams conducted like IPMAT by IIM Indore for integrated MBA program.

Feel free to ask if you have any more queries. All the best!!
