5 Study Strategies That Actually Work
Exam season is stressful enough without wasting time on study methods that do not work. Research in cognitive psychology has identified which techniques actually improve learning and which ones just feel productive. Here are five strategies backed by evidence.
1. Active Recall
Instead of re-reading your notes, close them and try to recall the information from memory. This is harder and less comfortable than passive review, but it is significantly more effective.
A landmark study by Karpicke and Blunt (2011) found that students who practiced retrieval produced 50% more correct answers on a final test than students who studied by re-reading or creating concept maps.
How to do it with StudyDeck: Use the quiz feature. Taking practice quizzes forces active recall, and the immediate feedback helps you identify gaps in your knowledge.
2. Spaced Practice
Spread your studying over multiple sessions rather than cramming everything into one sitting. Even if the total study time is the same, distributing it over days produces better retention.
How to do it with StudyDeck: Use the flashcard system daily. The SM-2 algorithm handles the scheduling for you, so you always review at the optimal time.
3. Interleaving
Instead of studying one topic exhaustively before moving to the next (blocking), mix different topics within a single study session. This feels harder but builds stronger connections between concepts.
How to do it with StudyDeck: When configuring a quiz, select multiple chapters instead of just one. The questions will be shuffled across topics, forcing your brain to switch between different types of problems.
4. Elaboration
When you learn a new concept, explain it in your own words. Ask yourself "why does this work?" and "how does this connect to what I already know?" This creates deeper encoding than surface-level memorization.
How to do it with StudyDeck: Use the short-answer questions. These require you to formulate your own response before seeing the sample answer, which naturally encourages elaboration.
5. Concrete Examples
Abstract concepts become more memorable when connected to specific, concrete examples. When studying a principle, try to come up with your own real-world example of it in action.
How to do it with StudyDeck: The calculation questions in subjects like Secure Software Systems give you concrete scenarios to work through. Instead of just memorizing that buffer overflows are dangerous, you calculate the actual memory layout to see how an exploit works.
What Does Not Work
For completeness, here are popular techniques that research has shown to be less effective:
- Highlighting and underlining. Feels productive but does not engage active processing.
- Re-reading notes. Familiar text creates an illusion of knowledge without actual retention.
- Summarizing. Slightly better than re-reading but still passive compared to retrieval practice.
The key insight across all effective techniques is the same: learning should feel effortful. If studying feels easy, you are probably not learning as much as you think. The strategies that work best are the ones that challenge you to retrieve, apply, and explain, not just recognize.
