An AI tutor for the SAT questions you got wrong

The hour after a practice test is when mistakes are easiest to fix. Pick one, talk it through on a shared whiteboard, and let the tutor lead you to where it went wrong instead of reading you the answer.

TestPrep AI Tutor is a voice tutor for SAT practice-test mistakes. After a practice test you choose a question you got wrong; the tutor already has the question, your answer and the correct one, and works through it with you on a shared whiteboard with the Desmos calculator open. It gives hints before answers, records what kind of mistake it was, and your first 2 wrong questions are free.

How a session starts

  1. 1

    Finish a practice test

The practice test screen. A question like this one, answered wrongly, is where an AI tutor session begins.
On screen

Four things open at once

Your voice, the whiteboard, the calculator and the question itself.

You think out loud

No typing. It stays quiet while you work and steps in when you take a wrong turn.

A shared whiteboard

Pen, text, shapes and highlights. It reads your handwritten step and carries on from there.

The exam's Desmos

The same graphing calculator as the test. It sees what you entered, so a right method typed wrongly is told apart from a wrong method.

It names the mistake

Each question is logged with the kind of error behind it, so a repeating pattern becomes visible.
Hints

Hints before answers, one rung at a time

The tutor climbs a fixed ladder of help. It starts at the bottom, moves up only when the rung below has not worked, and never skips one. Ask for the answer and it gives it.
  1. 0

    Watches

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

  2. 1

    Try again

    “Have another look at the answer choices.”

  3. 2

    Points

    “Read the second sentence of the passage again.”

  4. 3

    Asks

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

  5. 4

    Targeted hint

    “There is a sign slip. What happens when the minus moves across?”

  6. 5

    Shows one step

    It writes that step on the board and hands the rest back to you.

  7. 6

    Full solution

    Only once the guided attempts are used up, or when you ask for it.

The record

Every question leaves a short record

When a question closes, the tutor logs the kind of mistake, how far up the ladder it had to go and whether you found the error yourself. The audio and the drawings are not kept.
