Have you considered partnering with programs like QuestBridge? Their scholarship changed my life. They also offered a junior-year mentorship program with a college admissions newsletter and a complimentary essay-review. I think there's a chance here to collaborate in 9th, 10th, and 11th grade.

Also, are there any plans to offer non-English services? A lot of recent immigrant families would benefit from tutors who are bilingual in their language.

Going from a primarily low-income school to a good college showed me how much of the achievement gap in college between poor and wealthy students simply comes down to tutelage. This kind of work is really important - kudos to your team.
