AI Tutorial
👨🏻🏫 Use AI as a personal tutor to learn anything

In this tutorial, you will learn how to use ChatGPT's Study and Learn mode to get tutoring-style guidance that breaks problems into steps, checks your reasoning, and adapts to your level instead of just giving you answers.
Step-by-step:
In ChatGPT, click the "+" icon on the chat composer, select "More," then activate "Study and learn" mode
Describe your learning goal (e.g., "Teach me how to program in Python" or "Help me solve this finance problem")
Answer context questions the AI asks, then follow the step-by-step guidance as it nudges you toward solutions rather than providing direct answers
Use for comprehensive understanding and problem-solving skills; switch to Regular mode for quick facts or content generation
