Spaced repetition (SR) is a powerful study technique. It involves reviewing material at strategically spaced intervals to boost long-term memorization. By spacing out these review sessions, SR reinforces information before it fades from your memory.

Noji will prompt you by asking you to rate your familiarity with each card. Cards marked as Easy will appear less frequently, while those marked as Again will be shown more often. This method ensures you concentrate on the material that requires the most practice.

You can adjust the number of new cards you wish to study daily in the deck settings. Alongside new cards, you will also review previously learned flashcards. During each study session, Noji starts with cards you've practiced before, then it adds the cards that you have up for review. When done with all cards, Noji will notify you when the next set is ready for review.

The intervals between card reviews are vital in SR due to the nature of human memory. SR leverages the spacing effect, a principle that suggests information is better retained when learning sessions are spread out over time rather than crammed together. If you require immediate revision, you can switch to the General Repetition algorithm.

Spaced repetition is designed for sustained study, not quick crams. While immediate results aren't typical, incorporating SR into your daily routine will improve your memorization and reduce overall study time over the long term.

The forgetting curve demonstrates how quickly information can be forgotten. SR alters this curve by recalling information at spaced intervals, thereby enhancing retention. Reviewing a flashcard over days, weeks, and months is more effective than multiple repetitions in a single day.

SR determines the frequency of your flashcard reviews. Each successful recall extends the interval before the next review. Initially, you might review a card the next day, then in two days, four days, and so forth. Over time, these intervals can extend to weeks or even months.

When reviewing flashcards in Noji, you have four response options to rate your recall:

Noji uses your responses to automatically schedule the next review of each card, optimizing your study sessions for maximum retention.

Scientific research supports SR as more effective than repetitive, short-term studying. By incorporating SR into your study routine, you can transform your learning process and achieve better results with less overall effort.
