Business Management Studies

Sorry, to say dear, but doing BBA with these academics is not recommended. What you will do with these marks in future. I would suggest you retake class 12th exams and score good marks and then do BBA. Some low-class colleges will give you admission for money but that will not help you.

Boards marks have nothing to do with VIT admission but one should have 60% marks in physics, chemistry and maths. You will get admission in VIT University by writing VITEEE exam only otherwise it's not possible.

First of all, clear your all backlogs and then start the preparation of CAT and other management entrance examinations. Your graduation marks will have a bad impact, but you can eradicate it by scoring a high percentile.

You have a good academic profile. A good score in CAT preferably above 98 percentile will be good enough to get a call from IIMs. Just prepare well for CAT join a good coaching institute and test series. Apart from CAT score, a good performance in WAT/PI is also needed to grab a seat in IIM.

Some of the top CAT coaching institutes are:
Alchemist Institute
TIME Institute
Mindworkzz
Career LauncherAnkGanit
IMS Institute
Tathagat Institute
