SAT Math
Free, research-anchored Digital SAT Math practice. Diagnose which mistake patterns are costing you points. Drill only those, with feedback after every question. Type it in grid-in format, because a quarter of the section has no choices to lean on.
Practice
Three modes, one workflow
01 · Diagnose
Topic diagnostic
Ten-item topic assessments where every wrong answer is a real, named mistake pattern. Each result routes you to the specific drills that fix what tripped you up.
Start with Unit 102 · Drill
Targeted drills
One mistake pattern at a time, varied scenarios, feedback after every question. Reached from your diagnostic result.
03 · Grid-in
Typed-answer practice
Student-produced response items with no choices to lean on. Type your answer; a wrong value still maps back to the mistake that produced it.

Why mistake-targeted, not problem volume
Most SAT Math points are lost to a short list of repeatable mistakes: a sign dropped in a distribution, an inequality symbol left unflipped, a middle term missing from a squared sum, f(x) read as multiplication, and the classic trap of solving correctly and then reporting the value the question never asked for. The test is engineered around these; every distractor is one of them in disguise.
If you keep making a mistake, more mixed practice with it intact reinforces it. The fastest score gain comes from identifying which two or three patterns are costing you points and drilling exactly those. That is what Mistake Master is built to do.
