Spaced repetition

7-day study plan

1. Day 1Understanding the 'Forgetting Curve'
   Read

   Imagine you are learning a complex Physics formula like the Lens Formula. You understand it perfectly in class, but two days later, you can barely remember where the minus sign goes. This happens because of the Forgetting Curve, a concept discovered by Hermann Ebbinghaus. He found that our brains are programmed to discard information very quickly unless we prove that the information is important by reviewing it. For most Indian students, the pressure of huge syllabuses makes this curve even steeper because we are constantly cramming new data. The Forgetting Curve shows that within 24 hours, you might forget up to 50% to 80% of what you just learned. By the end of thirty days, you might only retain 2-3% if you never look at it again. This is why you feel like you are starting from zero during your pre-board exams. The secret is to interrupt this curve. By reviewing the information at specific intervals, you reset the curve and make the memory 'stickier' each time. To start, you must change your mindset from 'finishing the chapter' to 'maintaining the chapter.' Today, look at a topic you studied yesterday. Instead of re-reading the whole page, try to write down the main headings from memory. Notice how much has already started to fade. This awareness is the first step toward mastering spaced repetition. You are not failing if you forget; you are simply human, and your brain needs a reminder before the curve hits the bottom.

Revision notes

• Spaced repetition is a learning technique that involves reviewing information at increasing intervals over time.
• It's based on Hermann Ebbinghaus's 'Forgetting Curve,' which shows we forget information rapidly initially, then more slowly.
• The goal is to review material just before you're about to forget it, strengthening your memory each time.
• This method makes learning much more efficient than cramming, as it optimises review timing.
• Tools like Anki, Quizlet, or even a simple box system with 'daily,' 'weekly,' 'monthly' slots can be used.
• Always combine spaced repetition with active recall: try to remember the answer before revealing it.
• This technique is highly effective for memorising facts, formulas, vocabulary, and definitions.
• It transforms short-term knowledge into durable long-term memory, ideal for competitive and board exams.
