Concept map

  1. Reconnaissance notes: separate observation from inference

    Information gathering is useful when it improves the next question. Record source, time and confidence to turn scattered clues into testable hypotheses.

  2. Q&A · Decisions & explanations

    Explain the correct choice and why the alternatives fail.

  3. Safe practice & evidence check

    Record your own decision or output, then compare it with the expected result.

Follow the concept map, or go directly to practice if you know the prerequisites. Choose your own pace; there is no daily article quota.
