Dear student,
First of all i would like to congratulate you for scoring 84% in your 12th boards. It's good to see that you want to persue BBA further. Its a very good undergraduation course for those who want the core knowledge of Business managment.This course gives you an insight of the basics of Business administration which serves you further in MBA. So if you really want to have a knowledge of Business you should go along with BBA. With 84% you can get good colleges like Amity University,Babu Banarsidas, Lucknow University. You can also go for other colleges like Narseemonji and Symbiosis.
All the best. I hope this was helpful to you.
