Frequently asked questions

Most prep gives every student the same question sets. StudyPlanet chooses each question from your answers so far, stops drilling a skill once you've shown it, and brings it back on a spacing schedule. Your time goes to what you're actually missing.

Every answer shows where you are in each of the SAT's skills. You get questions just past what you can already do, where you're about 60–75% likely to be right, because that's where points come from. Your speed counts too, since the SAT is timed. Skills you've mastered come back for quick reviews just as they start to fade, so they're still there on test day.

Every question and explanation is written by the StudyPlanet team to the Digital SAT's published specifications. Each one is checked for a single correct answer and solved independently before any student sees it, and nothing is generated on the fly. Once a question is live, we track how it performs on real answers and rewrite the ones that don't hold up. We never copy questions from official tests.

They follow the same structure: Reading and Writing, then Math, two modules each, with the second module getting harder or easier based on the first. Question counts and timing match the real test, as do the core tools: a timer, mark for review, answer elimination and the reference sheet.

We report a range, not a single number, and always label it an estimate. Ranges are calibrated against released official practice tests and narrow as you answer more questions.

Seven days with one full-length practice test: the full Digital SAT with adaptive second modules, an estimated score, a breakdown by skill, and explanations for every question. No card is required, and the trial never turns into a paid plan on its own.

The monthly plan renews each month until you cancel, which you can do anytime from your account. The 3-month and 1-year plans are a single payment and simply end. We'll never charge you again unless you choose to.

You can request a refund within 7 days of purchase if you've answered fewer than 10% of the questions in your plan and haven't started a full-length practice test. After that, or once you've used more, purchases aren't refundable. Monthly plans can be canceled anytime, which stops future charges.

Yes. Practice works in any modern browser on a phone, tablet or computer. For full-length tests we recommend a laptop or a tablet with a keyboard, since that's closest to test day.

We collect only what we need to help you study, never sell data, and show no ads. Payments are handled by Stripe, so card numbers never touch our servers. Students must be 13 or older, and you can delete your account and its history at any time.
