Video-Driven Digital SAT & ACT Prep for an Effective Approach

Created by Kimani Williams, PhD

The Digital SAT and ACT curricula used at Tutoring Machines were methodically and ingeniously designed by Kimani Williams. After tutoring and teaching thousands of students, and continually increasing students’ scores for over a decade, he decided to profoundly and positively impact students from all over through education.

He designed test prep programs that are based not only on content, but also on strategies and techniques, which are readily understood and reproducible by students from many different backgrounds. The courses also take into consideration the demanding schedules of high school students by making the lessons short, effective, and fun.
