What Is Spaced Repetition?

Spaced repetition is a revision technique where you review material at increasing intervals over time. Instead of studying something once and hoping you remember it, you revisit it after 1 day, then 3 days, then 7 days, then 14 days. Each review strengthens the memory and slows down the rate of forgetting.

The Science Behind It

Spaced repetition is based on the forgetting curve, discovered by Hermann Ebbinghaus in 1885. Without review, we forget approximately 70% of new information within 24 hours. But each review session 'resets' the curve, making the memory stronger and longer-lasting. After 4-5 spaced reviews, information typically moves into long-term memory.

How to Use It for GCSE and A-Level Revision

Step 1: Study a topic (e.g., trigonometry). Step 2: After 1 day, test yourself on it (don't re-read — test). Step 3: After 3 more days, test yourself again. Step 4: After 1 week, test again. Step 5: After 2 weeks, test one final time. By this point, the information should be securely in your long-term memory.

Making It Practical

The biggest challenge with spaced repetition is keeping track of what needs reviewing and when. This is why digital tools are so valuable. StudyVector's spaced repetition system automatically schedules review sessions for topics you've previously studied, so you never forget to revisit material.

Combine With Active Recall

Spaced repetition is most effective when combined with active recall. Don't just re-read material during review sessions — test yourself. Try to answer questions from memory, then check your answers. This dual approach is the gold standard of effective revision.
