The problem this solves
“I want to learn deeply, not just widely. How do I combine the two?”
Primary keyword: spacing and depth
What you'll learn
- Why surface-spaced learning fails
- How to schedule deep dives
- A two-week alternating schedule
- A review of the depth of the reviews
The science behind it: Spaced Repetition
Spaced repetition is the practice of reviewing material at increasing intervals so that each review happens just as the memory is about to fade.
Why it matters
Spacing turns forgetting from a threat into a teacher: the small effort of remembering against growing intervals produces dramatically more durable memory.
How to apply it
- Schedule reviews at growing intervals: one day, three days, a week, two weeks, a month.
- Use an SRS app or paper box system to track what is due.
- Allow some forgetting to happen between sessions; the struggle is the mechanism.
Common mistakes
- Reviewing only on the day before an exam.
- Re-doing the entire deck every session instead of trusting the schedule.
- Conflating difficulty with failure and re-scheduling too aggressively.
