/What it is

Attempting a quiz before any study creates a cognitive gap your brain wants to close. When you later encounter the correct answer in your study material, your brain flags it as high-priority and encodes it more deeply. The failure isn't a problem — it's the entire mechanism.

Developed by researcher Manu Kapur. Students who failed first consistently outperformed students who were taught correctly first.

/How to do it

  1. Find a practice test, quiz, or past exam for your subject
  2. Attempt it cold — no notes, no studying, no preparation
  3. Answer every question, even if you're guessing — commit to an answer
  4. Mark your results — note every wrong or guessed question
  5. Study the material — but only the topics on your gap list
  6. Your brain is now primed to absorb the gap topics deeply
  7. Retest with a different paper to measure improvement
