How to Study, Like Your Hippocampus Is Watching.

Most studying advice is a soft, expensive lie. Highlight things. Re-read your notes. Watch a YouTube explanation at 1.5×. None of it sticks because none of it engages the machinery the brain actually uses to file information.

What actually works

• Retrieval, not recognition. Close the book and try to write the idea back out.
• Spacing. The same fifteen minutes, spread across three days, builds five times the memory of a forty-five-minute block.
• Sleep. Memories consolidate at night. Cramming at 2 a.m. trades tomorrow's recall for tonight's anxiety.
