Dear Kavita, most scholarships are either Merit based or need based. And Uttarakhand scholarships are run by Social Welfare Department of Government of Uttarakhand. There os one Post Metric Scholarship for ST Category students from Class 11 until Doctoral studies. You can register here for that Scholarship at their official page: https://scholarships.gov.in/fresh/loginPage
