Every question you missed comes back here — tomorrow, then every few days — until it is automatic. Get one right and it waits longer. Miss it again and it's back the next day.
Re-reading feels safe; re-fighting is what works. This page only shows questions your own answers said you were about to forget — and each one reappears exactly on the schedule your memory needs. Short sessions, daily. Five cards a day beats an hour of re-reading.
