🧠 Study Skills & Note-Taking · Lesson 1 of 6
How memory works
Encoding, storage, retrieval — and why rereading fools you.
Three steps
| Encoding | Getting information in — paying attention and making sense of it |
|---|---|
| Storage | Keeping it — memories strengthen with sleep and repetition over time |
| Retrieval | Getting it back out — on an exam, in a conversation, when you need it |
The forgetting curve
In the 1880s Hermann Ebbinghaus showed that we forget much of new material within days unless we revisit it. Each time you successfully recall something, forgetting slows down. That is why one long cram session fades fast, and several short reviews last.
The illusion of fluency
Rereading your notes feels good: the material looks familiar, so you think you know it. But recognizing is not recalling. On the exam there are no notes to recognize — you have to pull the answer out of memory. Study the way you will be tested.
Sleep is part of studying
During sleep, the brain consolidates what you learned that day. Pulling an all-nighter before an exam cuts the very process that stores the material. Seven to nine hours is a study strategy, not a luxury.
Tip
💡 After reading a page, close the book and say out loud what it said. If you can’t, you didn’t learn it yet — you only saw it.
✏️ Practice: your turn
- Read one section of a textbook, then close it and write everything you remember
- Compare with the text: what did you miss?
- Notice the difference between “it looks familiar” and “I can explain it”
- Plan your sleep for the night before your next exam
✏️ Study planner: turn your exam dates into a day-by-day plan
