About FLEX SAT and AP Exam Prep

FLEX SAT and AP Exam Prep is comprised of 3 main parts:


In a class setting, FLEX Principal Instructors introduce concepts and strategies. Students immediately reinforce their learning with in-class handouts. Instructors review homework and frequently missed questions in class.

Homework & Time Management

Students reinforce their learning with homework. FLEX offers students the option to complete homework in timed sessions in-center. This allows participating students to build testing stamina and time management skills.

Diagnostic Testing & Progress Reporting

Approximately once per month, students take full-length diagnostic tests to accurately evaluate progress. When available, real exams from prior years are used.
