Every year, thousands of students experience the same frustration — mastering a topic one evening, only to find it has slipped away by the next morning. This is not a failure of intelligence or focus; it is how the human brain naturally works. In 1885, German psychologist Hermann Ebbinghaus mapped this phenomenon through what is now known as the forgetting curve. His findings revealed that we can lose nearly 70 per cent of newly learned information within twenty-four hours if it is not reinforced.
Ebbinghaus also offered the solution: spaced repetition. By revisiting the same material at carefully timed intervals, we can significantly improve long-term retention. A quick review within a day, followed by three to five repetitions over the next week, can raise recall levels from 30 per cent to over 90 per cent. In essence, revision is not a formality — it is the bridge between learning and lasting memory.
The method is simple but powerful. Use flashcards or digital tools such as Anki to automate review cycles. Write short summaries by hand — the physical act of writing strengthens neural pathways. Highlight sparingly, focusing on key ideas rather than entire paragraphs. Read actively: question yourself, explain concepts aloud, and avoid passive rereading. Treat revision like a workout — brief, consistent, and deliberate. Miss one session, and the curve takes its toll.
Examination success is rarely about extraordinary intellect. It is about disciplined repetition and an understanding of how memory works. The world’s premier institutes do not merely test knowledge; they reward consistency. Begin tonight: revisit today’s lesson, even for ten minutes. Defeat the forgetting curve — and build your own learning curve instead.
