What cognitive science says actually works — and why most students study in exactly the wrong way
Last updated March 2026
From Dunlosky et al. (2013) — the most comprehensive meta-analysis of study techniques
Practice testing (flashcards, practice questions)
Highly effective across subjects, ages, and retention intervals
Distributed practice (spaced repetition)
Spreading study over time dramatically outperforms massed sessions
Elaborative interrogation (asking "why?")
Generating explanations creates deeper encoding
Self-explanation (working through why something is true)
Better than passive reading, especially for procedural content
Re-reading
Creates familiarity, not recall. Very widely used, very low effectiveness.
Highlighting / underlining
Negligible benefit over passive reading. Widely used, poorly effective.
Summarisation
Useful for high-prior-knowledge students; limited benefit for novice learners
Attend the lecture or read the material for the first time. Your goal is not to memorise — it's to understand the structure and context. Take notes actively, asking yourself "why" and "how" throughout.
Action: Immediately after, upload your notes to StudyCards AI and generate your flashcard deck for that material. The earlier you create cards after first exposure, the better the card quality.
This is the most critical review. The Ebbinghaus forgetting curve drops most steeply in the first 24 hours. A short active recall session within 24 hours of learning preserves most of what you encoded.
Action: Study your new flashcards in Anki. Be honest about difficulty ratings. This session doesn't need to be long — 20–30 minutes is enough to prevent the initial retention crash.
Follow Anki's spaced repetition schedule. Review your daily queue every day without fail. Cards you find easy get pushed out further; hard cards come back sooner. Each review strengthens the memory trace.
Action: 20–45 minutes of daily reviews. Add new cards from each new lecture concurrently. Don't let the queue build up — consistency beats intensity.
Shift focus to applying knowledge under exam conditions. Past papers, practice question banks, and timed tests reveal exactly where your flashcard knowledge isn't yet translating to exam performance.
Action: Continue Anki reviews daily. Add new flashcards for any gaps revealed by practice questions. Focus new card creation on application-style questions, not just definitions.
No new material. Review your Anki queue (which will be light at this point — you've been spaced-reviewing everything). Focus on past papers and any weak areas identified.
Action: Prioritise sleep. Research consistently shows that sleep-deprived performance is significantly worse, and that reviewing before sleep is especially effective for consolidation.
This depends entirely on the exam, not on a general rule. But here's what the research says about study time allocation:
StudyCards AI generates your flashcard deck from any notes in seconds. Export to Anki. Follow the system above. Stop re-reading — start retrieving.
