How Students Should Use AI

AI can be a powerful learning assistant, but it shouldn’t replace actual studying.

A simple approach is:

Learn → Ask AI → Verify → Practice → Write Yourself

For instance, if you struggle with a math topic, first study the basics. Then ask AI to explain it differently, solve some examples, and practice similar questions yourself.

This method helps you use AI as a tool, not as a crutch.
