Master Your Exams: The Science Behind Effective Study Strategies

Most students confuse studying with mere exposure—rereading notes, highlighting pages or rewatching lectures simply feeds information to your brain. True learning happens when you actively pull information out. Decades of research in cognitive science show that retrieval practice—testing yourself without looking at answers—builds stronger, more lasting memories. A 2006 Psychological Science study found that students who used retrieval practice retained twice as much information a week later compared to those who just reread their notes. Another vital principle is spaced repetition. Hermann Ebbinghaus charted the forgetting curve in the 1880s and found we lose about 70% of new material within 24 hours without review. Revisiting topics at planned intervals helps lock knowledge into long-term memory.
