考官重点
官方报告整理常见失分点
- Struggling with fractional indices, especially negative powers such as \(16^{-\frac{3}{2}}\).
- Incorrect conversion between units before simplifying ratios, like mixing grams and kilograms.
- Forgetting to write the full equation of a line when asked to 'find an equation', leaving it only as a gradient or partial form.
- In non-calculator papers, making basic subtraction errors under exam pressure (e.g. \(180 - (360 \div 6)\)).
常见误区
- Believing that the area scale factor is the same as the linear scale factor in similarity questions.
- Assuming that a negative gradient is positive when finding the perpendicular bisector line equation.
- Confusing simple interest formulas with compound interest under multi-year compound settings.
失分原因
- Failing to state clear geometric reasons when asked to explain similarity (need corresponding angles, common angles).
- Losing accuracy marks by not leaving the final answer in the exact requested format (e.g. leaving a surd unsimplified or not in standard form).
- Omitting the minus sign during algebraic factorisation of quadratics.
