See the trap before you pick the wrong answer.
Take practice that behaves like the real test, then see exactly why the answer you picked looked right. Five minutes at a time, on your phone.
No account needed to start. Free to use. No ads.
The wrong answers are designed. Your review should be too.
Most explanations tell you why the right answer is right. Here is the other half: why the answer you reached for looked right, and the pattern behind it.
This is a real question from the app, not a mock. Pick a choice and see what happens.
Maria is 3 times as old as Tom. In 5 years, Maria will be twice as old as Tom.
How old is Tom now?
Three steps. Five minutes. Free.
Pick what to drill.
Five modules cover Reading, Math Strategy, Grammar, AP essays, and Common App essays. Sessions take about five minutes. Pick what you want to work on or let us suggest based on your weak areas.
Spot the trap.
Each question has one right answer and three carefully designed wrong ones. You pick an answer, mark how sure you are (low, medium, high), and submit.
See the pattern.
On reveal we tell you which kind of trap was at play and which evidence supported the right answer. Over time you start recognizing patterns before you pick.
What are you preparing for?
Digital SAT
Reading, Writing, and Math, with full-length tests that route to a harder or easier second module the way the real one does.
- ·Reading: the wrong-answer traps in passage questions
- ·Math: pick the fastest path, then avoid the wrong-question trap
- ·Grammar: spot the rule actually being tested
- ·Full-length tests scored 200 to 800 per section
ACT
English, Math, and Reading, plus the optional Science section, on the 2026 format and scored 1 to 36 with a composite.
- ·English: translate the stem, then pick the revision
- ·Math: 45 questions in 50 minutes, so pacing is the skill
- ·Reading: four passages under real time pressure
- ·Science: reading graphs and experiments, not memorized facts
AP essays. Map your evidence to the rubric row a grader actually scores, including AP Calculus practice. Application essays. Work out what a Common App prompt is really asking you to show, before you write the essay you wish they had asked for.
Built for accuracy, not for a bigger number.
A big practice library is worth nothing if an answer key is wrong or a question does not behave like the real test. That is the fastest way a prep tool loses you, so we built against it.
An app can hand you the answer to one question. That does nothing on test day, when it is just you and four choices. We show you why the wrong answers are built to look right, so you catch them on your own.
Every question is solved from scratch, independently, before it ships, and the answer keys are hidden from whoever solves them. If a solver disagrees with the key, nothing ships until a person settles it.
Full practice tests are scored on the College Board's published conversion (200 to 800 per section) and the ACT's 1 to 36 scale. The conversion is official, the questions are ours, so read the number as a solid estimate.
- 01Written to one named skill and one specific trap on the current exam
- 02Math and figures verified against the numbers, option by option
- 03Solved blind by independent solvers who cannot see the key
- 04Reading answers must be supported by the passage on your screen
- 05Duplicates and re-skinned questions rejected
- 06Flag it in one tap and a person reviews it
50+ full-length tests for when you've run out of Bluebook.
98 questions, two hours, Reading & Writing plus Math, structured the same way as the real digital SAT, including the harder second module that catches people off guard. You get a 200 to 800 scaled score per section using the College Board's published conversion, plus the skills that tripped you up the most. New to the test? A short placement gives you a rough starting range in a few minutes first.
What you'll actually use.
What students usually ask.
Are these the real questions from the SAT?
No, and that is the whole point. The drills are written to look and feel like the real test, but they are not a bank of leaked questions to memorize. Each one is built around a specific way the real exam tries to trip you up, so you practice catching the pattern instead of the answer. When that same setup shows up on test day, you see it coming.
How do I know the questions and answer keys are actually correct?
Every question is solved from scratch and independently checked before it ships, so the right answer is right and the wrong ones are real traps. We also re-checked all 19,600+ questions in one pass and fixed every error we found. If you ever spot one that looks off, flag it in a tap and a person reviews it. The full process is written up on our methodology page.
I've run out of official practice tests. Can this help?
Yes, that is one of the most common reasons people show up here. Once you have been through the official Bluebook tests, you need more that behave like the real exam, including the harder second module that catches people off guard. We have 50+ full-length practice tests across the digital SAT and the ACT, scored the way the real exams are (the SAT on the College Board's published conversion, the ACT on a 1 to 36 scale).
Should I take the SAT or the ACT?
Colleges accept both equally, so take the one you score better on. The digital SAT is shorter and adaptive, with a built-in calculator for all of Math. The ACT is faster per question and includes a Science section. The quickest way to decide is to try a short drill of each here and see which one feels more natural, then focus your practice there.
Is it free?
Yes, fully free to use. No paywall, no credit card, and no ads. If we ever add paid features, we'll tell you in advance and won't take away anything you already have.
Where does the practice-test score come from?
Your SAT sections are converted with the College Board's published raw-to-scaled tables, and ACT sections use the published 1 to 36 scale. The conversion is official, the questions are ours, so read the number as a solid estimate rather than an official score. Give it about a 60-point band on the SAT, since real scores move between forms and test days.
