Hello Sudhanshu,
Many state governments have introduced common entrance test for admission to the hotel management colleges. But others allow admissions based on marks obtained in 12th. You will have to check on the website of your state.

BBA is professional course, it relates theory with practical knowledge most of the subject are theoretical in nature, so logically you don't need to work hard in this. Management is like professional degree, there is no need of any particular skills you have to pursue all kinds of skills. A manager need to have all the skills, because you do know which skills you required at your organization.
