| Mistake | Why It Happens | How Past Papers Correct It | | :--- | :--- | :--- | | | Students focus on numbers, not the measurement system. | JISMO often mixes cm and m in the same graph. Past papers train you to check units first. | | Assuming "common sense" | Real-world intuition conflicts with scientific models (e.g., "cold flows into a room" vs. heat flows out). | Past paper answer keys explicitly state the correct scientific phrasing. | | Skipping the diagram | Students read the text and ignore the visual data. | Many JISMO questions cannot be answered without diagram analysis. Practice builds visual literacy. | | No time for Section C | Spending 35 minutes on easy multiple choice. | Past papers teach you to skip and return. If a calculation takes >2 minutes, flag it and move on. |
