Need Help learning about Low Income and Minority Based Scholarships

Here’s a more specific question that is genuine–Are the scholarships targeted for low income/minority students going to be at the same caliber of competition as the Coca Cola Scholarship? Students winning national awards, curing cancer, major leadership roles, etc?

Are there multiple scholarships awarded by Questbridge and/or others out there? How many scholarships are awarded yearly to low income/minority students. Is it a Lottery Pick, or do they really have a chance to win a scholarship? Is it worth the effort to apply to these type scholarships?
