The use of spaced repetition in review sessions is a powerful feature that significantly enhances user knowledge retention. This method leverages the psychological spacing effect, which posits that information is more easily recalled if it is studied and reviewed periodically over increasing intervals of time rather than through cramming or massed practice.

Spaced repetition encourages learners to revisit material at strategically determined points in the future, allowing their brains to reinforce the connections made during initial learning. This has been shown to improve long-term retention of information. By spacing out review sessions, users can consolidate knowledge and minimize forgetting, making the learning process more effective.

In comparison, while immediate testing after every lesson may provide instant feedback and recognition of areas needing improvement, it does not optimize retention over a longer period as effectively as spaced repetition does. Weekly tutoring sessions and group study sessions can be beneficial for collaborative learning and addressing specific questions, but they do not inherently focus on the timing of review, which is crucial for embedding knowledge in memory.
