SAT Reading & Writing

Know why every answer is right.

Practice the SAT Reading and Writing skills one question at a time — and read, for every question, the reasoning behind it. Written in English and in Chinese.

The question bank downloads on first launch, and works offline after that.

The explanation is the app

Most practice apps tell you whether you were right. This one tells you what the question was doing, why the right option is the right option, and what trap each wrong option was built to set — and it is written for that specific question, not generated from a template.

Predict before you answer

Write down what you think the answer will be before you look at the options. It does not have to be correct — it has to be yours, because the gap between what you expected and what was true is the thing worth seeing.

See the trap you fell into

Get a question wrong and the explanation names the trap your wrong answer was built on — too broad, too narrow, the opposite of what was stated, and a dozen other shapes a wrong option can take.

Tap any word

Every word in a passage, a question or a technique note opens its definition and its pronunciation, in the language you are reading in. The dictionary is inside the app, so it works with no connection at all.

A journal of what you got wrong

Only wrong answers are kept, each one with your prediction and your own sentence about what you were thinking. They are grouped by the mistake you made — in your words, not a category picked for you.

Private by construction

No account. No sign-up. No ads, no tracking, no third-party analytics. The app downloads its question bank from our server and sends an anonymous heartbeat: an installation id, the app version and platform, and a country derived from the connection. Your answers, your journal and your settings never leave your device — deleting the app deletes them.

A question you can argue with

A practice app that shows its reasoning is worth more than one that shows a number.
