Adaptive, like the real thing
Module 1 mixes easy, medium and hard questions. How you do decides whether Module 2 is the easier or harder version, as on test day.
SatPrep builds a fresh full-length adaptive SAT every time — two modules per section, the real timing and tools — then shows your estimated score and exactly which skills to work on.
Why SatPrep
The digital SAT adapts to you and runs on a screen. Practising on paper misses half of it. SatPrep doesn't.
Module 1 mixes easy, medium and hard questions. How you do decides whether Module 2 is the easier or harder version, as on test day.
Every test is assembled fresh from 600+ original questions, favouring ones you haven't seen, so test number ten is as new as test number one.
Countdown timer you can hide, graphing calculator, reference sheet, highlighter, answer eliminator, mark for review and Apple Pencil scratch paper.
An estimated 400–1600 score after every test, with accuracy by skill and a list of your weakest areas to drill next.
Targeted practice by domain, skill and difficulty with full explanations, plus a mistakes queue that brings back what you got wrong. Always free.
Built for iPad with Apple Pencil, and runs natively on Mac. Progress syncs through iCloud. One subscription covers 3 devices.

Each section has two modules, and how you do on Module 1 decides whether Module 2 is easier or harder, as on the real test. Question counts, timing, the break, the calculator, the reference sheet, highlighting, answer elimination and mark-for-review all follow the digital SAT. Scores are estimates: the College Board doesn't publish its exact scoring.
