Most exam-prep tools lump every wrong answer into one bucket: "you got it wrong, try harder." PrepMethod separates the three root causes so the fix is specific.
Knowledge gaps are the easiest to spot — the student hasn't been taught the concept yet. Process gaps are subtler; the student knows the concept but picks the slower route. Performance gaps are the hardest to catch: everything is understood, but pressure or timing breaks the chain.
Each gap needs a different response. This is the heart of the PrepMethod method and why every session ends with a clear, specific next step.
