The Science of Learning
Traditional studying (reading and re-reading) wastes time. Cognitive science shows that spaced repetition, active recall, and interleaving dramatically improve retention and test performance.
1. Spaced Repetition
Review material at increasing intervals (1 day, 3 days, 7 days, 2 weeks, 1 month) to move information into long-term memory.
Why it works:
Forgetting curve shows we lose 50% of info within 24 hours. Spaced repetition resets the clock and strengthens neural pathways by 40-50%.
2. Active Recall
Test yourself instead of passively reading. Use flashcards, practice exams, or teach someone else to retrieve information from memory.
Why it works:
Recall strengthens memory 2-3x better than passive reading. Testing effect improves retention by 50%.
3. Interleaving
Mix different topics or problem types instead of blocking (learning one topic deeply, then moving on).
Why it works:
Interleaving forces your brain to discriminate between concepts. Exam performance improves by 30-40%.
Optimal Study Plan
Learn Domain 1 concepts with videos (1 hour)
Practice Domain 1 questions + review other domains (1 hour)
Learn Domain 2 + active recall on Domain 1 (1 hour)
Spaced repetition: Flashcards daily, full exams weekly
