Watch your SAT Math score climb to 800.
Most prep apps hand you points that mean nothing. Here, the only numbers on screen are real: what today's practice has cost you, and what we think you'd actually score.

A score, not points
No invented XP. Practice runs on a daily budget of 800 points that a wrong answer costs and a right one earns back, and your projected exam score is a real estimate built on the same kind of ability model the College Board uses.
The trap, named
Every wrong answer on the SAT is engineered around one specific mistake. When you fall for one, we tell you exactly which mistake it was — that's the part that actually moves your score.
The real calculator
The same Desmos graphing calculator you get inside Bluebook on test day, one tap away on every question. Practice the tool, not just the math.
Where these questions come from
Every question here is written from scratch, modelled on the published SAT Math domains and difficulty bands — and every wrong answer carries the specific mistake that leads to it. Nothing is copied from an official test.
