TestPrep AI

It works the question you got wrong through with you

Finishing a practice test is where the work starts. TestPrep AI sits down with your mistakes: it does not read out the answer, it asks you the question and gets you to find where you went wrong.

It starts from one mistake

When the test ends, your results list every question you got wrong or left blank. Pick one, press AI Tutor, and the lesson begins — the tutor already has the passage, the choices, the answer you gave and the one you needed.

How it works

Four things are open at once: your voice, the board, the calculator and the question.

You work out loud

No typing. It stays quiet while you think and steps in when you take a wrong turn — in whichever language you speak to it.

You share a board

Pen, eraser, text, box, circle, highlight. It reads the step in your own handwriting and carries on from there; your marks and its marks stay on separate layers.

The exam's Desmos is open

The same calculator you used in the test. It sees what you typed, so right algebra entered wrongly is told apart from wrong algebra.

It names the mistake

Sign slip, misread question, missing concept? Recorded per question, so the pattern becomes something you can see.

It won't lead with the answer — and won't withhold it

The tutor climbs a ladder. It starts at the bottom and moves up one rung at a time, never skipping. Ask for the answer and you get it: no haggling, no “try once more first”.

  1. Watches

    If you are working, it stays out of the way.

  2. Try again

    “Have another look at the choices.”

  3. Points

    “Read the second sentence again.”

  4. Socratic question

    “Are we solving for x here, or for 2x?”

  5. Targeted hint

    “There's a sign slip — what happens when you move the minus across?”

  6. Shows one step

    Writes only that step on the board; the rest is yours.

  7. Full solution

    Once the guided attempts are genuinely spent.

Every question leaves a record

When a question closes, the tutor classifies it: which kind of mistake, how far up the ladder it had to go, how many hints, whether you got there in the end and whether you found it yourself. The audio and the drawings are not kept — what remains is the short record that shows your repeating mistake.

Questions people ask

What language does it teach in?
It opens in the site's language and then follows yours. Answer in English and it continues in English; say “Türkçe devam et” and it switches. The question itself stays in English — that is how you will meet it on test day.
Do I have to speak?
The lesson runs on voice, but you can mute whenever you like and work on the board instead — it reads your handwriting.
Will it ever just tell me?
Yes. It won't start there, but ask and you get it. There is also a “Show the answer” button on screen at all times.
How does the time work?
Your first two wrong questions are free. After that it draws on minutes you bought, and those belong to your account rather than to one test.
