Key points
- If you can’t explain it simply, you don’t understand it.
- Use teaching to expose gaps early — before they cost marks.
- The method is a loop: explain → find gaps → repair → simplify again.
The 4-step Feynman loop
1
Choose one concept (small enough to finish)
Example: “DKA management” is too broad. Start with “Why ketones rise in insulin deficiency” or “How to calculate corrected sodium.”
2
Teach it to a child (plain language)
No jargon. No “because guidelines say so.” If you must use a term (e.g., “anion gap”), define it in one sentence.
3
Circle your stumbles (those are your gaps)
Any moment you reach for a phrase like “basically” or “it just happens” is a gap. Write the exact missing link as a question.
4
Repair the gap, then rebuild with an analogy
Go back to the source (notes/Q-bank explanation/guideline), fix the missing link, then create a clean analogy that you can recall under pressure.
Make it exam-proof (the upgrade)
After you can explain it simply, convert your explanation into 5–10 flashcards: definitions, triggers, first-line actions, and the “common trap.” You’re turning understanding into retrieval strength.
Use this technique for high-yield “confusion magnets”: acid–base, ECG patterns, ABG interpretation, antibiotic selection, anticoag reversal, paeds dosing, and stats/EBM. It front-loads pain so you don’t experience it in the exam hall.
