Revolution Prep is redefining how students learn by transforming the traditional tutoring relationship through the power of live, one-on-one instruction with a full-time, professional tutor. We understand the impact that a fantastic educator has on a students academic confidence, and therefore invest deeply into the growth and development of our academic advisors and faculty to be teachers, mentors, and role models. As a result, our students achieve dramatic growth in our four core metrics: 1) Better grades, 2) Better test scores, 3) Greater love of learning, and 4) Lower Stress. At Revolution, our philosophy is guided by the belief that any student can learn with the right support. Beyond Grades. Beyond Tests. Beyond Tutoring. Revolution Prep.
