A shared board
The tutor writes the steps one under another; you write with the pen, and it reads your handwritten step and carries on from there.
TestPrep AI Tutor talks you through the questions you got wrong
When a practice test ends, pick a mistake on your results page and the lesson starts. The tutor won't just read out the answer: it asks you, writes the steps on the board and lets you find where you went wrong.
- Your first 2 mistakes are free (up to 10 minutes)
- No card needed to try it, just your account.
- Works on SAT, GMAT, GRE, PTE, IELTS, TOEFL and ACT practice tests.
How it works
Finish a practice test
Your results page lists every question you got wrong or left blank.
Open the AI Tutor
Go in from the AI Tutor card on your results page, then pick the lesson language, how it runs and the tutor's voice.
Talk it through
The tutor asks, you answer; the steps go up on the board and hints come when you're stuck.
Move on
Press “Finish this question” once you've got it. Your first 2 mistakes are free; after that you carry on in 30-minute blocks.
What a lesson has
You choose how it runs
“Step by step, together”: the tutor asks, you solve. “Let the tutor explain”: it talks you through the solution and you stop it wherever you get stuck.
In your language
Start the lesson in any of 20 languages; after that it follows whichever language you speak. The question itself stays in English, as it is on test day.
The exam's own Desmos
The same calculator you use in the SAT practice test is on screen. The tutor sees what you type, so it can tell a right method with a mistyped expression from a wrong method.
Writing, coached against the rubric
You go through your Writing Task 1 / Task 2 text against the IELTS band descriptors: it shows where the score comes from using your own sentences, and you make the fixes. It never writes the text for you.
You work out loud
No typing: you talk it through. Interrupt whenever you like, ask a question, or say “got it” and move on to the next one.
It won't lead with the answer, or withhold it
It asks you first and gives hints one step at a time when you're stuck. Ask for the answer and you get it; the “Show the answer” button is always there too.
Your mistake types, in your panel
Each question's mistake type is collected in your panel, exam by exam: how many questions each type came up on, and which ones, each linked to its test's results.

What it doesn't do
- It doesn't predict your score or promise a higher one.
- It works on the practice tests you finish, not on question-bank or homework questions.
- It doesn't review IELTS or TOEFL Speaking, doesn't re-score PTE pronunciation, and never writes your text or homework for you.
- It doesn't replace a human teacher; our one-to-one tutoring is a separate service.
Questions people ask
Which exams does the AI Tutor work on?
SAT, GMAT, GRE, PTE, IELTS, TOEFL and ACT practice tests, including the free diagnostic tests. When the test ends, the lesson starts from a question you got wrong or left blank on your results page.
How much is free?
Your first 2 wrong questions are free, once per account, for up to 10 minutes. There is no card to enter to try it; you just need to be signed in.
How is it charged after that?
You buy time in 30-minute blocks, up to 8 blocks (4 hours) in one purchase. The price is shown in the site's currency. Unused minutes stay on your account and carry over to your next practice tests.
Will it just tell me the answer?
Yes, if you ask. It starts by asking you and giving hints, but say “just tell me” and it does. The “Show the answer” button is on screen for every question, except Writing tasks, which have no single right answer.
What language does it teach in?
It opens in the language you pick (any of 20) and then follows whichever language you speak. The question stays in English, as it is on test day.
Do I need a microphone?
The lesson runs on voice, so your browser will ask for the microphone; headphones and a quiet room help. You can mute whenever you like and carry on by writing on the board.
Are lessons recorded?
No audio is kept. A written transcript of the lesson and a short note per question (the type of mistake and how many hints it took) are kept with your account, and deleted when your account is deleted.
