The Ultimate Guide to Active Recall & Spaced Repetition
Two evidence-based techniques that dramatically improve long-term memory compared to passive rereading.
What is Active Recall?
Active recall means retrieving information from memory — e.g., testing yourself, using flashcards, or writing what you remember without looking. The act of retrieval strengthens the memory trace much more than re-exposure alone.
What is Spaced Repetition?
Spaced repetition schedules review sessions at increasing intervals to fight forgetting. Combine this with active recall (flashcards + spaced intervals) for a powerful combo.
Practical Steps
- Create small question-based flashcards (digital like Anki or paper index cards).
- Review with active recall: try to answer before checking the card.
- Space reviews: review today → 2 days → 7 days → 21 days (adjust per difficulty).
Quick Routine
- Make 10–20 cards after each study session.
- Do a short 20–25 minute recall session daily for new material.
- Use spaced intervals — decrease frequency as accuracy rises.
Takeaway
Active recall + spaced repetition = efficient studying. Less time, better retention. Start small and be consistent.
