hello dear,
BBA is the most preferred choice after engineering. While surfing net, you can find lot of BBA colleges in Bangalore but choosing the best one is little tough. Here are top BBA colleges in Bangalore:

• Alliance University
• Jain University
• Christ University
• Koshys Institute of Management Studies
• Sri Bhagawan Mahaveer jain college
• Institute of Business Management and technology
• Presidency college

I'll suggest koshys Institute of Management Studies for BBA because they have 100% placements all over the world. Other than BBA they also offer MBA, BCA and other management courses. They also have hostel with good food, wifi and other additional facilities.
hope thsi would help you.
