Our mission

As former tutors, we have personally seen the massive unfair advantage 1-1 instruction and mastery learning can make in a child’s education. With the pandemic, the education gap has grown larger than ever as those who can afford tutoring are taking advantage of it to get ahead, and those who can’t are left behind, often missing out entirely on learning when they miss key concepts required for moving forward with their learning. It is our mission to close this gap by providing the highest quality free tutoring available to any student who needs it.
