Research Findings (2025):

"Students using spaced-repetition software like Anki scored 6.2 to 10.7% higher on standardized exams compared to those using traditional study methods."

A 2025 study found that medical students using spaced repetition achieved significantly higher post-test scores (16.24 ± 2.37) than control groups (11.89 ± 2.94) with p < 0.0001.

Why Spaced Repetition Works:

• The Forgetting Curve

  Memory decays over time. Spaced reviews interrupt this decay at optimal points, strengthening the memory each time.

• Desirable Difficulty

  Retrieving information when it's slightly difficult to remember makes the memory stronger than easy retrieval.

• Active Recall

  Actively retrieving answers is far more effective than passively re-reading material.
