Thinking about your own thinking: planning how you will learn, monitoring whether you understand, and adjusting strategies when something is unclear.
Metacognition includes questions like: Do I actually know this, or do I recognize it? What will I do if I get stuck? Which part of this lesson needs another pass?
Strong learners explicitly monitor comprehension. That awareness pairs well with technical study—for example when using AI agents: you judge when to trust output versus when to verify assumptions.
