Inside, you'll find 32 SAT-style problems across all four math domains, each with step-by-step calculator instructions for Desmos, TI-84, and NumWorks. Filter by skill level, switch between calculators, and track your progress as you go. Built for students preparing on their own and for families working with a tutor, this guide pairs perfectly with a structured test prep plan. Use it to practice the calculator techniques that save real time on test day.
