100 Hard Math
These questions mirror the hardest problems on the real SAT — the ones appearing from 17-22 on math modules. Master them and you'll be able to handle any question with confidence.
What makes these questions hard
Every question here targets the 700+ scoring range — the kind of problem the SAT saves for positions 17-22 of a math module. Most of them stack two or three skills in a single prompt: a quadratic hidden inside a function translation, an exponent rule buried in a percent-change setup. You can know each skill on its own and still stall when they combine.
The set covers the topics the hardest slots draw from most often — quadratics and their vertices, exponential functions, systems with no or infinitely many solutions, circles, trigonometry, and volume. Many answers are constants you have to solve for rather than clean multiple-choice picks, which is exactly how the real test raises the ceiling.
How to use the video explanations
Each question has its own video walkthrough. Make a real attempt on paper before checking anything, then watch the video whether you got it right or not — the method shown is often faster than the one that worked for you. If you missed a question, redo it from scratch a few days later instead of rewatching.
