It’s a long time ago now, but a young woman I know got accepted at HYP–all 3 of them. Her classmates were stunned because as far as they knew, she had very limited ECs. It turned out that her parents spoke very limited English and she had a brother with Down’s syndrome. Taking care of him and helping her parents navigate the system to get appropriate care for him was her principal EC. Very few of her classmates, if any, knew that.They found out when she won a major scholarship for kids from poor families.
