60-Second Timed Challenge
One minute. As many grammar questions as you can answer. Your best score is saved on this device — try to beat yourself tomorrow. Instant decisions only: no feedback mid-run, speed matters.
Why a timer?
Fluency is grammar under time pressure. In conversation nobody gives you twenty seconds to choose has gone over have went. The timed challenge trains your brain to retrieve correct forms automatically — the skill that makes you sound fluent instead of careful.
