The science behind it: Interleaving
Interleaving is the practice of mixing different but related topics or problem types within a single study session, instead of blocking practice on one type at a time.
Why it matters
Interleaving makes practice harder in the moment, but builds the discrimination and flexibility needed to pick the right method when facing new problems.
How to apply it
- Mix problem types within a study set instead of finishing one type before starting another.
- Alternate between related but distinct skills, such as different brush strokes or different algorithms.
- Return to earlier topics across sessions to keep the mix active.
Common mistakes
- Believing blocking is more efficient because each item feels clearer.
- Treating interleaving as random scrambling rather than as deliberate mixing of related material.
- Giving up on interleaving because it feels harder than blocking.
