4

I’m not sure what you want with “4.” Could you tell me the subject and what you’d like to do? Here are a few quick options:

• Create a 4-question mini-test on a topic (with solutions)
• Provide 4 practice problems in a subject (e.g., calculus, stats, linear algebra)
• Give 4 key concepts or formulas to memorize
• Solve problem #4 from a set you have (paste the problem)

Tell me the subject, level (undergrad/grad), and your preference, and I’ll generate it.
