Four guided questions (retry until right), then six on an 8-minute clock. The timed set auto-scores and feeds your sub-skill Error Log. New here? Read the handout first.
Work each question and explain your reasoning aloud. A wrong answer gives you a hint and lets you try again — no penalty for a second look.
6 questions, 8 minutes, answers locked until you finish. Press Start timed to unlock them.
