What Is Spaced Repetition and Should You Use It?

You have heard the term spaced repetition thrown around but never got a straight answer on what it is or whether it earns its hype. It explains the method in plain English, why the spacing effect works, and whether it suits how you learn. Good for anyone curious about study techniques who wants the honest verdict before committing to flashcards.

<task>
1. Explain spaced repetition in plain English: reviewing information at increasing intervals as it becomes more familiar, exploiting the spacing effect
2. Explain why it works: the brain strengthens memories that are retrieved just before forgetting occurs
3. Give two practical ways to use it: Anki (free flashcard software) and low-tech alternatives (physical flashcards with a box system)
4. Name the types of learning it works best for: factual recall, vocabulary, formulae - and note where it is less useful: conceptual understanding and problem-solving
