Tutors, test-prep centers, and schools can purchase sets of deeply-discounted vouchers that entitle their students to enroll at no cost to them in our Tutored Student Membership, our suite of resources that act as a force multiplier for test-prep programs that assign practice tests to students as homework between prep sessions and/or that use our SAT Math Orange Book as the central text in their math instruction.

The membership provides students with the interactive digital edition of the SAT Math Orange Book, our indispensable course on Mastering Desmos for the Digital SAT, online Autoscoring Answer Forms (AAFs), which produce SAT practice test score reports that include instant access to hi-def video explanations for every one of the 5,000+ questions on the released SATs, math problem topic categorization, direct page citations to our SAT Math Orange Book, and instant viewing of any math problem in our SAT Math Topic Explorer (SMTEx), which supplies lists of similar problems from real tests and which can open the Digital Orange Book right the page where the relevant explanation is presented. Students can also browse the video explanations directly if they prefer to use bubble sheets and manual scoring.

Students who are using our SAT Math Orange Book, the digital edition of which is included, under the guidance of a tutor or prep center gain access to autoscoring answer forms for all the section and chapter practice problems in that text along with linked video explanations for every practice problem in the Orange Book.
