Most doubts arrive vague: "I didn't get rotation" or "this chapter makes no sense". Carry that to class and your teacher spends the few minutes they have for you finding out what you mean. A short session with an AI the night before can turn the fog into one precise question, so the teacher's time goes on the real gap.
Does the quality of your question really matter?
Yes, more than the number of questions you ask. In a classic study of tutoring sessions in algebra (Class 7) and research methods (college), Arthur Graesser and Natalie Person found that student questions were about 240 times as frequent in tutoring as in classrooms (Graesser and Person, American Educational Research Journal, 1994).
The more useful finding was this: once students had some experience of tutoring, their achievement rose with the quality of their questions, while the number of questions they asked was not linked to achievement (Graesser and Person, 1994). The authors also noted that students partly found and repaired their own knowledge gaps by asking, but needed training to do it well. A sharp question is a skill, and you can practise it.
What turns a vague doubt into a sharp question?
A doubt has four levels; each tells your teacher more.
Topic: "I don't understand banking of roads."
Task: "I can't do the question where the road is banked and there is no friction."
Step: "I get stuck when I write the normal force."
Reasoning: "I wrote N = mg cos θ, as on an inclined plane, and my speed came out wrong. Why is that not right here?"
A Level 4 question shows what you tried, where it broke and what you expected, so the answer fixes the idea, not just the sum.
How do you use AI to prepare questions for your teacher?
The trap is letting the AI simply explain everything. In a field experiment with nearly a thousand high school maths students, those who practised with a plain ChatGPT-style tutor got 48% better grades during practice, but once the AI was taken away they scored 17% lower than students who never had it; a version with prompts designed to protect learning largely avoided that drop (Bastani et al., PNAS, 2025). So use the AI to question you, not to replace your thinking.
Write your doubt as it is, however vague. Add the question or textbook lines it came from.
Paste your own attempt, even if it is half done. (We explain why in showing your working to AI before you ask.)
Ask the AI not to solve it yet, but to ask you short questions, one at a time, until together you find the exact step where you go wrong.
Stop when you can finish the sentence "I expected ___ but got ___ because I assumed ___."
Write that as one question in your notebook, with your working beside it.
This is the kind of work an AI tutor that teaches, rather than one that only answers, is built for. Fermi's AI tutor holds a line of reasoning across a session, notices where you are stuck, and decides whether to explain, ask or show, which is what step 3 needs.
Worked example: banking of roads
Riya, in Class 11, writes: "I don't get banked roads." The AI asks what she wrote for the forces. She lists weight and normal force, and says she used N = mg cos θ. The AI asks which way the car's acceleration points. She says "down the slope", then stops: the car moves in a horizontal circle, so its acceleration points horizontally towards the centre.
Her question for class becomes: "On an incline I use N = mg cos θ because there is no acceleration perpendicular to the slope. On a banked road the acceleration is horizontal, so is that why N cos θ = mg instead, which makes N bigger than mg?"
Her teacher can now confirm the idea in a sentence and spend the rest of the time on the real gap: choosing axes from the direction of acceleration. If you keep making the same kind of wrong-method mistake, the Fermi Problem Library has a step-by-step solver that explains the reasoning rather than printing an answer.
What if the AI already answered your doubt?
Still take it to class, in a shorter form: "I think the answer is X because Y. Is that right?" AI can be confidently wrong, and a teacher checking your reasoning takes seconds.
Before class, check you have:
one question, written in a single sentence
your working, with the step that broke marked
what you expected and what you got
one follow-up, if the teacher has time
