Discover science-backed strategies for retaining more in less time — from spaced repetition to active recall methods used by top students worldwide.
Exam Prep
1. Spaced repetition — review before you forget
Spaced repetition is a learning technique where you review material at gradually increasing intervals. Instead of studying a topic once and moving on, you revisit it after 1 day, then 3 days, then 7 days, then 2 weeks. Each review session strengthens the neural pathway before it fully fades, making the memory more durable over time.
Tools like Anki or MizaLearn's built-in flashcard system use algorithms to schedule your reviews automatically based on how confidently you recalled each card.
Key insight
Reviewing material at increasing intervals is far more effective than re-reading notes the night before. Students using spaced repetition retain up to 80% of content after 30 days compared to just 20% with massed practice.
2. Active recall — test yourself, don't just re-read
Active recall means closing your notes and forcing yourself to retrieve information from memory — rather than passively reading or highlighting. The struggle of retrieval, even when you get it wrong, strengthens memory encoding more than any passive method.
