Avoid careless errors (the fastest free score boost)

Careless errors are the easiest thing to fix, and they move scores quickly.

• Two-pass answering: answer confidently, then do a 3-second trap check.
• Rule sentence: force yourself to state the rule in one sentence before clicking.
• Don’t switch late: only change answers if you can name the mistake in your first rule.
• Environment: avoid multitasking. A quiet 10 minutes beats a distracted hour.

Use the timed test once you’re accurate — it trains attention under pressure.
