Can an LLM quiz me?
Yes. Paste your notes and ask the model to put one question at a time, wait for your answer, and explain what you missed. This active recall is more effective than asking for a summary.

How do I know the explanation is correct?
Ask for the source or the derivation, and check anything you will be examined on against your textbook. Models are most reliable on standard school and college material and least reliable on recent or niche topics.
Can an LLM replace a tutor?
For explanations on demand, largely yes. For motivation, exam strategy and noticing what you keep avoiding, no. It works best alongside a teacher or study group.
