Key points
- Your constraint is fragmented time, not intelligence.
- Micro-sessions work when they are retrieval-first, feedback-later.
- Design a “dead time” protocol you can execute anywhere.
The Concept
When working full-time, you rarely get long uninterrupted blocks. Micro-dosing exploits the spacing effect by inserting frequent retrieval opportunities into the day. The rule is strict: daytime sessions are for questions and recall, not reading. Deep explanation review happens later when you have stability. This prevents your prime time being consumed by low-yield browsing and keeps your learning curve compounding.
Scientific Evidence
Distributed practice improves long-term retention. Mobile learning can be effective when designed around active engagement (questions, retrieval) rather than passive scrolling.
Implementation Strategy
1
Phase 1: Map your dead time
Identify predictable gaps: commute, pre-round, lunch, waiting for results, admin queues. You only need 3 micro-windows/day.
2
Phase 2: The 15-minute protocol
Minutes 0–12: timed Q-bank (10–15 items) OR Anki reviews. Minutes 12–15: flag misses and write one-line reason for each miss.
3
Phase 3: Evening consolidation (20–30 minutes)
Review only flagged misses. Patch with minimal notes: one rule, one discriminator, one flashcard. Avoid rewriting entire topics.
4
Phase 4: Weekly integration
Once weekly, do a longer mixed block to train random selection and timing, then update your Red/Amber/Green tracker.
