Can we write in pencil for psle in maths paper 2?

My daughter did that too. Pen and pencil. Checked with MOE teacher's- will not be penalised.

Should be B Only.


X and Y can be different or same materials e.g. both can be iron or X can be iron and Y is glass. There is no way to ascertain. But Z and Y must be different materials e.g. Z is wood, Y is iron.

Thanks. That’s what my girl thought too but her friend put neither. Reason being that the materials Y and Z could have different masses.

It was not mentioned that the 3 solids are identical nor it is of fair experiment.

Did the question state if X, Y and Z are of the same size?

I think it is 4.

eg. Y and Z could both be made of wood, but Z could be hollow.

Is there any moderation for subject grade? Or it must be above 90 to get an A*? Any info from moe website? As I heard it is strictly base on raw score…no moderation at all regardless of the difficulty of paper
