Crush Your SAT Prep

SAT practice for Android, by TEZZVO.

Practice for the whole SAT, Math and Reading & Writing, at your own pace. When you miss a question, the app shows you why, and brings it back later.

In testing, not in a store yet. Crush Your SAT Prep is not on Google Play yet, so there is nothing to download from this page. When it is available, this page will say so and link to it.

Learn why, not just what

Every answer explained

After each question you see why the right answer is right, and why each of the others is tempting.

A card for each skill

A “How this works” card gives the rule and a worked example, one tap away from a question you missed.

A come-back list

The questions you missed wait in a list. A question leaves it once you answer it correctly on two different days.

Where to start

A short check-in for each section shows you where to begin, and a practice score estimate on the 200–800 scale says how many answers it is based on. It is a rough read on the practice you have done here, not a test-day score.

A look at it

Learn why, not just what. An Advanced Math explanation: the question, the right answer marked, and why it is right, with a How this works button.
Reading and Writing, passage and all. A Craft and Structure question with its passage shown above the question.
Know what to do next. The home screen names your weakest topic so far and offers to practice it, with free questions left and progress for Math and Reading and Writing.

What is in it

Both sections

Math: Algebra, Advanced Math, Problem-Solving and Data Analysis, Geometry and Trigonometry. Reading & Writing: Information and Ideas, Craft and Structure, Expression of Ideas, Standard English Conventions. About 800 questions in all.

Checked keys

Every answer key is checked by a second, independent solve before the question is served. A flag on every question lets you report a problem, and a question you report is set aside from your practice until the questions are updated.

Made to read

Math in real math notation, and figures drawn to scale. Light and dark themes. Text grows with your phone’s font size, up to 200%, without being cut off. Press and hold an option to rule it out.

Offline

The questions live on your phone, so you can practice without a connection. An optional daily reminder comes at a time you choose.

What it costs

The first 40 questions are free, with no account and no card. One purchase, paid once, unlocks the rest. There is no subscription and there are no ads. Every explanation, every “How this works” card, your come-back list and your score estimate stay free, before and after the 40.

What it does not do

It has no full-length practice test: the real SAT is adaptive and is taken in Bluebook, College Board’s testing app, which has free full-length practice tests on a computer or an iPad. It has no built-in calculator, so practice with Desmos, the graphing calculator used on test day. It is in English only.

Your data

No account and no sign-in. Your practice stays on your phone. The app sends anonymous usage data, which you can turn off in Settings.
