考官重點
官方報告整理常見失分位
- Incorrect rounding or failure to quote calculated answers to two decimal places or two significant figures where specified (such as rate or resistance calculations).
- Omitting key units or using incorrect units, especially matching Hz with GHz or expressing acceleration as m/s instead of m/s².
- Mislabeling diagrams or incorrectly orienting arrows in food webs, pointing away from the predator instead of the direction of energy flow.
常見誤解
- Believing that viruses can be eradicated with antibiotic treatments, ignoring that antibiotics are strictly targeted to bacteria.
- Assuming alloys have a regular layer arrangement that slides easily, rather than understanding that different-sized atoms disrupt the lattice.
失分原因
- Forgetting to plot more than half the grid during graph-drawing tasks, losing critical marks for scale selection.
- Failing to write down intermediate math steps in physics equations, losing error-carried-forward (ECF) marks.
