Knewton is revolutionizing test prep by using cutting-edge adaptive learning techniques to identify each student's particular needs and build for each student a course designed to maximize his or her score as efficiently as possible.

Knewton tags all of its content—practice questions, text explanations, and instructional video—at the most granular level possible. The adaptive learning engine tests students' mastery of hundreds of very specific skills tested on the exam and assembles a mixture of practice questions and review materials designed to provide the student with just what he or she needs—no more, no less—to achieve his or her goal score. Meanwhile, Knewton's superior teachers offer students an exceptional instructional experience—more hours of live instruction than anyone else in the industry—in the Knewton online classroom (or through archived versions of these lessons.

Len Swanson and Rob McKinley, makers of the two adaptive testing algorithms used on the GRE and GMAT, have created a third—Knewton's.
