I feel like my SAT scores are holding me back.

Your peers are no longer the other students at you HS. The numbers really working against you are that there is about 35,000 high schools in the US. Almost all of them will have at least one student like you. Many of them will have multiples. My DS’s HS likely has 25+ students like you. There just isn’t enough room at the top schools for all of the students that meet the academic standards.
