The midyears for many JC have ended and most of my students got their papers back. I notice a handful do not follow instructions very clearly. The instructions to candidates always state clearly as shown.

ANSWER ALL QUESTIONS! Its very upsetting that students give up the entire question at (i) because they cannot show/ prove (i). They need to realise that (ii) can still be well-attempted and they should not throw marks away freely.

NON-EXACT answers! What exactly is non-exact answers? Consider $\frac{389.8}{8}=48.725$, this is exact so students should NOT round it off to 3 significant figures. On the other hand $\frac{389.8}{8}=55.6857142857 \approx {55.7}$ is correct as that is non-exact. Students should be more alert of such common pitfalls as they are throwing their answer marks.
