    Common Mistakes

    Common errors to avoid in your coursework

    • Assuming hybrid/electric vehicles can be treated the same as conventional internal combustion engine vehicles for glazing work without additional safety precautions.
    • Forgetting to isolate or disconnect the high-voltage system after the necessary waiting period, leading to potential shock hazards.
    • Failing to consult specific vehicle manufacturer instructions regarding glazing repairs, particularly concerning sensor recalibration or structural integrity.
    • Using improper tools or adhesives that could damage high-voltage cabling or interfere with electronic systems.
    • Misconception: All vehicle glass is the same. Correction: Laminated and toughened glass have different properties and are used in different locations for safety reasons.
    • Misconception: You can drive immediately after fitting a windscreen. Correction: Adhesive needs time to cure (often 1-2 hours) to ensure a safe bond; driving too soon can compromise the fit.
    • Misconception: Glazing is just about fitting glass. Correction: It also involves assessing damage, preparing the vehicle, and ensuring electronic systems like sensors and heating elements are correctly connected.

    How Students Lose Marks (Examiner Pitfalls)

    Common mark loss traps and how to write 100% full-mark answers

    Pitfall: Students often confuse the types of glass used in vehicles, especially laminated vs toughened glass, and fail to explain their specific safety properties and locations.
    ❌ Weak Answer (Loses Marks):Laminated glass is used for windscreens and toughened glass for side windows. Laminated is stronger.
    ✅ 100% Model Answer (Full Marks):Laminated glass consists of two layers of glass bonded with a PVB interlayer, which holds together on impact, preventing shattering and reducing injury. It is used for windscreens because it provides structural integrity and clarity. Toughened glass is heat-treated to create compressive stress, causing it to shatter into small, blunt granules on impact, reducing injury risk. It is used for side and rear windows because it breaks safely and can be easily replaced.
    Examiner Tip: Always link the glass type to its safety function and location. Use correct terminology like 'PVB interlayer' and 'compressive stress' to gain full marks.
    Pitfall: In practical or written assessments, students often miss the critical step of checking the vehicle's electrical systems (e.g., rain sensors, heating elements) before fitting a new windscreen, leading to damage or malfunction.
    ❌ Weak Answer (Loses Marks):I would clean the frame and apply adhesive, then fit the glass.
    ✅ 100% Model Answer (Full Marks):Before fitting, I would inspect the vehicle for any existing damage, check the condition of the glass frame, and identify any electrical components such as rain sensors, heating elements, or antennae. I would disconnect the battery if necessary, and ensure all connectors are properly aligned and reconnected after fitting. This prevents electrical faults and ensures the glass functions correctly.
    Examiner Tip: Always mention pre-fitting checks and electrical considerations. Examiners award marks for showing awareness of the whole vehicle system, not just the glass.
