Satified, answered

The product

Is Satified free?

Completely. There is no premium tier, no locked content, and no trial that expires. It costs nothing on day one and nothing on day one hundred.

Do I need an account?

No. There is no sign up, no login, and no email capture. Open the study app and the first question is seconds away.

Are there ads?

None. Nothing is being sold and nothing is tracked for advertising. The site exists to be used, not monetized.

Who built Satified?

One student, Mirza N. Baig, who wanted practice that matched real digital SAT difficulty without a price tag. The full story is on the about page.

The math

Does the question bank match the real digital SAT?

It is organized by the test's own taxonomy: 4 domains and 19 skills, weighted roughly the way the test weights them, about 35 percent Algebra, 35 percent Advanced Math, 15 percent Problem Solving and Data Analysis, and 15 percent Geometry and Trigonometry. Difficulty is calibrated to the real easy, medium, and hard tiers.

How is difficulty handled?

Every question carries a tier, easy, medium, or hard, matched to the difficulty bands the digital SAT itself uses. You can drill one tier on purpose, such as hard only for module 2 preparation, or mix them the way the real test does.

Are the answers actually correct?

Every answer, figure, and explanation in the bank of 1,483 questions has been independently verified, checked separately from the code that generates it. A drill bank with wrong keys teaches wrong math, so verification was treated as the most important feature of the site.

Why do questions regenerate?

Each question is a generator that rebuilds with new numbers, new context, and shuffled choices every time it loads. You end up mastering the pattern instead of memorizing the answer, and the bank never runs out.

The test

How does the adaptive practice test work?

Module 1 gives everyone 22 questions of mixed difficulty. Your performance routes you to a harder or easier module 2, exactly like the real test, and adaptive routing is a toggle if you would rather fix the difficulty yourself.

What is the timing?

Two modules, 22 questions each, 35 minutes per module: 70 minutes of testing for 44 questions, the same shape as the real digital SAT Math section. Pacing practice is half the reason to take a full simulation.

Is Desmos included?

Yes, the same built in Desmos graphing calculator the real test provides, available on every question. Learning when to open it and when to skip it is a scored skill in its own right.

How is it scored?

On the real 200 to 800 scale, using the adaptive structure: reaching the harder module 2 keeps the top scores available, while the easier module 2 tops out lower. Treat practice scores as honest estimates, not guarantees.

The AI tutor

Is the AI tutor free?

Yes. It is free, needs no account, and is built into the study app. It runs on free model tiers, so on rare busy moments it rests for a minute and then comes back.

What can the AI tutor do?

It can give a hint, explain the next step, name the skill being tested, or walk through the whole question. It already has the exact question, the verified correct answer, and the figure when there is one.

Will the AI tutor just give me the answer?

Not by default. It leads with hints and teaches the tested skill. Ask for the full walkthrough when you want it, and it will give the steps.

Can the AI tutor be wrong?

It can slip on arithmetic like any AI, so check its steps, ideally with Desmos. Because it is anchored to each question's verified answer, it will not send you toward a different final answer.

Can I use the AI tutor during the real SAT?

No. It is for studying before test day. On the real SAT you must follow College Board rules, and outside AI tools are not allowed.

How is the AI tutor different from ChatGPT?

It already knows the exact question, the verified answer, and the figure, so it stays on the SAT and will not confidently give a wrong final answer the way a blank chat box can. The full comparison has more.
