UWorld is powerful because explanations are deep and performance reporting is structured. But most candidates waste that power by ‘reviewing’ explanations passively. The correct move is to treat UWorld as a diagnostic instrument: it tells you *how you fail* — then you engineer a system to stop failing that way.
The common failure
Reading explanations feels productive and takes hours. It also produces weak recall. Your output must be prompts you can retrieve — plus a small error log you actually revisit.
The Bottom Line
- Every miss must be classified (knowledge vs misread vs reasoning vs timing).
- Extract one testable rule from every miss (10-second prompt).
- Retest only failures on Day 2 / Day 7, plus weekly ‘Top Errors’.
1
Step 1 — Run a timed block (create signal)
Timed blocks reveal the real constraints: attention, fatigue, misreads, and poor triage. Tutor mode is useful later — but it can hide the true failure mode.
2
Step 2 — Classify each miss (60 seconds total)
Label each miss: (A) Knowledge gap, (B) Misread/failed to notice key clue, (C) Reasoning error (wrong rule), (D) Timing/guessing. You’re building a *failure profile*.
3
Step 3 — Extract a single rule + a trigger
Write: “When you see X, do Y because Z.” The trigger must be specific (a threshold, a classic clue, a contraindication). This becomes your prompt.
4
Step 4 — Build a micro ‘error deck’ (not a notebook)
Errors go into a short list (30–60 items max). If it grows beyond that, your prompts are too broad or you’re logging low-value details.
5
Step 5 — Spaced retest + weekly consolidation
Day 2: retest all Reds. Day 7: retest Reds + Ambers. Weekly: retest the whole error deck and delete what is now automatic.
