考官重點
官方報告整理常見失分位
- Premature rounding of intermediate trigonometric steps (e.g. rounded sine values), leading to a final answer out of range.
- Failing to write down equations first in algebra problems that specifically ask to 'write down and solve an equation' (resorting to trial and error instead).
- Failing to adjust denominator values in 'without replacement' combined probability questions.
- Confusing 1 significant figure instructions with basic rounding or simply writing down exact calculator outputs.
常見誤解
- Believing 'Z-angles' is an acceptable geometric term instead of 'alternate angles'.
- Treating compound interest rate calculations as simple interest schemes.
- Writing vectors using coordinate notations (or division lines) rather than standard column vector syntax.
失分原因
- Assuming a perpendicular line to a segment bisects it by default, causing failure to find the true midpoint.
- In complete factorisation tasks, only taking out partial common factors (e.g., leaving 3 out of difference of two squares).
- Failing to convert decimal hours to minutes/hours format properly in speed calculations.
