Timed pandas assessment
Time limit: 45 minutes, 12 questions. Set a timer before you start; the page doesn't time you.
Each question is independent and starts from the same data: df (Juniper Lane orders), customers, cafe (Maple Street Cafe items sold), rentals (Harbor Bikes), daily (store days) and emp (employees). Online assessments score correct results only, so read each question for its edge case before you write code. Skip a question if you're stuck and come back to it.
