Hello

Yes, many scholarships are available based on the 12th-grade marks. including major government schemes like the Central Sector Scholarship (CSSS) for only eligible students, and some private foundations also give scholarships like Reliance, Mahindra and Infosys. Only those students who have high marks and are from the economically weaker section will be able to participate in these programs. I hope this information helps you.

Thank you.
