Why AI tutoring matters
Benjamin Bloom's 1984 research found that students who received one-to-one tutoring performed about two standard deviations better than those in conventional classrooms5. Human tutoring is expensive; AI tutors offer a scalable approximation. Early evidence is promising but mixed, and tutors work best alongside practice and feedback.
Personalized learning with AI: examples
- Diagnosing your level with a few questions, then adjusting difficulty.
- Explaining the same concept in different ways until it clicks.
- Generating practice questions on your weak topics.
- Building a study plan around your exam date.

The critique of AI personalized learning
Critics point to inaccurate answers, learners outsourcing thinking, privacy concerns and unequal access. UNESCO recommends human-centred use with teacher oversight6. The practical answer: use AI tutors to ask you questions, and verify important facts.
How to get the most from an AI tutor
- Tell it your goal and level ("I'm preparing for AZ-900 in three weeks").
- Ask it to quiz you one question at a time.
- Answer before asking for help.
- Ask "why" after every correction.
- Check readiness with an independent test, such as a free SOA scenario certification.
