How the Spaced Repetition Flashcard System Works

Nexelia’s flashcards use the SM-2 spaced repetition algorithm — the same method used by Anki. When you answer a flashcard, you rate how well you knew it (Easy, Good, Hard, or Again). The system schedules your next review automatically based on your rating.

Cards you find difficult appear more frequently. Cards you know well are shown less often. Over time this means you spend your revision time where it matters most.

Your due cards appear on your dashboard each day. Review them daily for best results — even 10 minutes per day compounds significantly over weeks.
