High-Yield Exam Strategy & Scoring Tips
Step-by-Step Mark Allocation
Always state the governing principle or formula first, write given values with standard SI units, substitute clearly, and highlight the final numerical answer with units in a box for full step marking.
Common Calculation Traps
Watch for unit prefixes (cm to m, minutes to seconds, g to kg, degrees to radians). In coordinate and ray optics problems, double-check Cartesian sign conventions before computing.

Frequently Asked Exam Questions & Concept Clarifications
Why does an airplane wing experience lift?
Air travels faster over the curved upper surface, lowering pressure above the wing compared to beneath it (Bernoulli lift).
