My Ds and som of classmate also put circle. Because pinhole is very small. draw light ray should be circle. :scratchhead:

My DS sd not difficult but a lot of comparisons in Booklet B. Thus, a lot of writing. Managed to complete the paper in time but no time to do checking.

[quote=\"Smurfiees\"]May I ask what did the psixes put for the shadow qn ? some put square , some put circle. May I know which one is the correct one ? And yes , mcq was v.easy . booklet b got a lot of comparisons .

i am a p6 student too. i think the ans is the circle cause if u draw two straight lines from the pin hole, the light will not be blocked by the square.

But the light rays passing thru the pinhole could go at a line parallel to the ground if the pinhole is small, then no light will shine on the screen at all, so the screen shuld be totally dark and thus the ans shuld be a square as the screen is square.[/quote]My son put circle

Hi, today is the last paper for DD and those who are not taking HMT.


Later will go DD school to 试探军情 and buy her and her friends some snacks for their mini party. DD is very happy as she only needs to come home at 4.30pm.

Oh, surprise to find out your DD does not take HMT. Still remember you top the CNY 成语 challenge with many of us leh.

But if you draw the lines to the screen, still can't see the circle coz the light is blocked by the square (circle is within the square). so it's square rite? unless i read the question wrongly.
