SAT Sphere FAQ: answers about plans, tools and the Digital SAT

SAT Sphere is an online prep platform for the Digital SAT. It combines a structured course of 8 modules and 75 lessons, 5,000+ SAT-style practice questions, timed practice tests, flashcards, a 28,000-word dictionary and the SAT AI tutor in one study plan.

The course has 8 modules: 4 for Math and 4 for Reading and Writing, with 75 lessons in total. Each lesson teaches one skill with worked examples and ends with SAT-style practice questions, so you can check your understanding before moving on.

Yes. The free plan needs no payment card and includes introductory materials, one full course module with its practice questions, the SAT dictionary, one flashcard deck and a small daily SAT AI allowance. Upgrade only when you want the rest of the course and tools.

The SAT Sphere website and its free resources (SAT guides, test dates, the blog and the University Hub) are available in several languages, including English, Spanish, French, German, Polish, Japanese and Korean. Course lessons and practice questions are in English only, because the Digital SAT itself is taken in English and practicing in the language of the test prepares you best.

No. SAT Sphere runs in any modern web browser on a laptop, tablet or phone. For full-length practice exams we recommend a laptop or tablet, because the real Digital SAT is taken on one in College Board’s Bluebook app.

Power-ups are the study tools around the course: flashcards, the SAT dictionary and practice tests. They help you memorize vocabulary and rules, look up unfamiliar words and practice under timed conditions.

Flashcards turn vocabulary, Reading and Writing rules and Math facts into short review sessions. SAT Sphere has 6,900+ cards organized into decks; Free and Premium include one deck and Premium Plus unlocks every deck.

A searchable dictionary of about 28,000 English words that often appear in SAT-style passages. Look up unfamiliar vocabulary while you study; the dictionary is included in every plan.

Practice tests follow the Digital SAT module format, with a separate timer for each module, and are included from Premium. When you finish, you get an estimated score that weighs accuracy and time per question, and you can review every answer. Premium Plus also lets you build custom practice exams from the sections and skills you choose.

The study plan is included from Premium. Enter your test date and when you can study, and SAT Sphere builds a schedule that spreads the course modules across the weeks before your exam.

Your dashboard shows which modules and lessons you have completed, along with your practice test results and flashcard activity. Use it to see which skills still need work before test day.

Premium unlocks all 8 course modules and 75 lessons, 5,000+ SAT-style practice questions, timed practice tests, a personal study plan and the SAT word dictionary. It also includes one flashcard deck and a small daily SAT AI allowance.

Payments are processed securely by Stripe, our payment provider. SAT Sphere never sees or stores your card details; we only receive a confirmation that the payment went through.

Prices are shown in the currency of your language version of the site, for example US dollars, euros, Polish złoty, Japanese yen or Korean won. The exact amount is always shown on the Stripe checkout page before you pay.

SAT AI is the AI tutor built into SAT Sphere. Ask it to explain a question step by step, give you a hint, clarify a grammar rule or Math concept, or write a similar question to practice with.

The full SAT AI tutor is part of Premium Plus. Free and Premium include a small daily allowance so you can try it; the allowance resets every day.

Open SAT AI from your dashboard and type your question or the problem you are working on. Short, specific questions such as “Why is answer C wrong?” get the most useful answers.

SAT AI covers both Digital SAT sections, Reading and Writing and Math. It can also help with study strategy, such as how to pace a module or plan your remaining weeks.

SAT AI is a helpful study partner, but like any AI tool it can occasionally make mistakes. Check its explanations against the lesson material, and if an answer looks wrong, let us know through the contact form.

Yes. SAT AI runs in the browser on laptops, tablets and phones, so you can ask a quick question wherever you study.

The Digital SAT has two sections: Reading and Writing (54 questions, 64 minutes) and Math (44 questions, 70 minutes). Each section is split into two modules, with a 10-minute break between the sections, for a total testing time of 2 hours and 14 minutes. It is taken in College Board’s Bluebook app, with the Desmos calculator built in.

Each section is scored from 200 to 800, for a total between 400 and 1600. The real Digital SAT is adaptive: your performance in the first module of a section decides whether the second module is easier or harder, which affects the score range you can reach.

You register through your College Board account, choose a test date and a test center and pay the registration fee. Seats fill up quickly in many countries, so check the SAT calendar in our resource hub and register well before the deadline.

Yes. Many students take the SAT two or three times, and some universities superscore, combining your best section scores from different test dates. Use your SAT Sphere practice test results to decide when you are ready for a retake.
