Common questions
The entire curriculum was hand-crafted by an instructor with over a decade of SAT experience. Every question was carefully selected to focus only on what actually matters. No filler, no unlikely edge cases, no wasted time. Each problem comes with a video showing how to solve it in the most efficient way possible. Watch, learn the approach, then practice it yourself. If you get stuck on anything, just watch how it's done and try again.
Everything. All four SAT Math domains broken down into every subtopic: Algebra, Advanced Math, Problem-Solving and Data Analysis, and Geometry and Trigonometry. Each subtopic is split into three difficulty levels (Easy, Medium, Hard) with dedicated video lessons and practice problems. Over 1,700 problems are solved on video so you can watch exactly how to approach any question type you're struggling with.
