555

Not sure what you need with “555.” Do you want a quick study aid or practice? Here are a few options—tell me which you’d like and your subject/level:

• 5-question quick quiz on your current topic
• 1-page concise summary (formulas, key concepts)
• Short study plan for an upcoming exam (timed, with breaks)
• Practice problems in a specific subject (math, physics, chemistry, stats, etc.)

What subject and level are you studying, and how much time do you have? If you were just saying “555” as a joke, I can join in—got a topic you want to cover?
