TestPrep AI Tutor talks you through the questions you got wrong
When your AP 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.
- You work out loud
- A shared board
- It won't lead with the answer, or withhold it
