About Us
At DOUBLE800, our primary focus is SAT and PSAT preparation, offering live courses and supplemental tutoring in Tucson, Austin and Chicago. Since our first prep class in Tucson in 2002, when a perfect SAT score was "double 800," we have instructed thousands of college-bound high school students with highly successful results. In fact, we believe the best way to convey our program efficacy is to list our clients' statistics* and testimonials.

Since all DOUBLE800 SAT/PSAT courses are owner-taught, parents and students can ensure that the instructors are both proficient and dedicated. By comparison, national test prep companies experience high turnover of their teachers, who are typically minimally-trained, part-time employees concentrating on their own career paths.

Another key distinction of our prep course, is the usage of actual College Board SAT* questions for studentsí practice tests. This is unequivocally the best method of preparation, as students become more familiar and confident with real SAT questions, patterns, solving techniques and anticipated score. In contrast, our corporate counterparts invent and publish their own synthetic SATs for test simulation and score prediction.

A final element of the DOUBLE800 program, is our realization that a large classroom is not the most conducive environment for SAT preparation. Invariably a discrepancy exists between studentsí ability levels and it is impossible to satisfy each class memberís needs. As such, we offer a unique method of instruction:
