4

Nice. Four can be a starting point. What would you like to focus on? Here are quick options. Tell me a subject and level, or just pick an option:

• 4-question mini-quiz on a topic you specify (with full solutions)
• 4-key concepts/definitions (with brief explanations)
• 4-step study plan for an upcoming exam
• 4 common pitfalls in a topic (and how to avoid them)

If you want, I can just generate 4 practice questions right now—tell me the subject (e.g., Calculus I, Linear Algebra, Intro Stats) and level.
