Ranjeet, usually a minimum of 50% is required in your 12th aggregate for BBA or BCA. Students from any stream can apply for BBA or BCA.

You can surely go ahead with any of these courses with 60% marks in your 12th boards irrespective of your category.

However, for your information, there is no BBA course in Sri Guru Gobind Singh College but there is BCA. You can check the courses list on its official website for further information http://www.sggscollege.ac.in/

I hope this helps you !
