The Science of Effective Revision: What Research Says
Decades of research have revealed which revision strategies actually work—and which are a waste of time.
What Doesn't Work
Highlighting and re-reading: Creates familiarity, not learning
Cramming the night before: Poor retention, high stress
Passive consumption: Watching videos without active engagement
What Does Work
Interleaving
Mix different topics rather than blocking by subject. This forces the brain to discriminate and strengthens learning.
Distributed Practice
Space out study sessions over time. Forgetting and re-learning creates stronger memories.
Elaborative Interrogation
Ask "why" and "how" questions. Connect new information to existing knowledge.
Practice Testing
The most powerful technique: test yourself repeatedly, even before you feel ready.
The Bottom Line
Work smarter, not just harder. Evidence-based revision techniques make every study hour count.
