Scoring

Correctness first; efficiency (time, keystrokes, steps vs an expert reference) adds a bounded bonus. Graders check outcomes, so any valid approach passes.

• Unproctored results are capped at L3 on the public certificate; you can book a proctored retake to confirm L4 or L5. Every certificate shows whether it was proctored.
• Retakes: wait 14 days per module, maximum 3 attempts per quarter. Your highest valid level shows on your profile.
