shiwenyi: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.
My DD says is a square....
