SAT math practice — every question, two ways to win it

No — they are original questions written in SAT style, covering the same algebra domains (Heart of Algebra, Passport to Advanced Math, Problem Solving & Data Analysis). Official practice lives with the College Board and Khan Academy; this set is for drilling the underlying skills with full worked solutions.

Every question here can be solved two ways: the algebra way and the Desmos way. The digital SAT gives you a built-in Desmos graphing calculator for the entire math section — so the fastest strategy is knowing both routes and picking per question. Each solution below shows the algebra; each tip shows the Desmos route.

Eight, growing over time. Quality over volume: each question has a verified worked solution (every answer on this page was checked with our own solver engine) and a Desmos strategy. More sets — including geometry and data analysis — are in development.

On the digital SAT, yes — a graphing calculator (Desmos) is built into the test app for all math questions, and you may also bring an approved calculator. There is no longer a no-calculator section.

Answer before revealing: the set only shows the worked solution after you pick. When you miss one, redo it with the VerifySolve calculator for that topic (linked below) using “One like it” until the method is automatic — then come back and re-run the set.

Yes — completely free, no sign-up, no app. The worked solutions are never paywalled.
