Gapwise: ACT & SAT Prep

Gapwise finds the gaps in what you know, helps you close them, and checks the result on questions you haven't seen. No ads. No subscription.

HOW IT WORKS

1. Find your starting point
Pick the ACT or the SAT. A short, untimed check for each section (English, Math, Reading, Science, or SAT Reading and Writing and Math) samples every skill and suggests where to start. Skip any question you want.

2. Learn it
A short lesson and worked examples show how each type of problem works, and why the wrong answers are wrong.

3. Practice
Every answer is explained as you go. Miss one? Note what happened (misread it, ran out of time, didn't know how) so you know what to work on. Practice anything mixes the skills you pick into one set, with the ones you missed first if you like.

4. Check yourself on new questions
Take 10 questions you haven't seen. Score 8/10 or better and a short "did it stick?" check with 5 more new questions opens.

5. Review anytime, and see what to work on next
Questions you've practiced come back, the ones you need most first. Recommended next points to the skills worth your time, based on everything you've answered.

6. Test-day strategies
Short lessons on pacing, smart guessing, ruling out wrong answers and plugging answers back in, each with a quick drill. Every skill lesson ends with quick-solve tips.

7. Timed sets
Practice at test pace, with 1.5x or 2x time, or with no timer. Mark hard questions and come back to them, then get a pacing report: time on each question, the ones that ran long, and what you got right within the time.

8. Practice tests
Take a full-length practice test for any section under test conditions: answers at the end, mark and come back, your choice of timer. See how you did on each skill, with the same pacing report.

GO AT YOUR OWN PACE
Nothing unlocks on a timer. Finishing the work and passing a check opens the next step. The starting check is never timed, and timers are always optional.

WHAT YOU SEE IS WHAT YOU DID
Results show exactly how many new questions you answered correctly, like "8/10 on new questions." Gapwise doesn't guess your test score.
