Hi Vanilla Cake

The source was from mrswongtuition - although I believe it has not been vetted by anyone. Therefore a student provided answer sheet most likely. So I hope no flaming of the source occurs (as a general request - not you specifically VC ) - I think she is just trying to help.

I am appending a screen shot of the answers provided below.

Answer is (3) as Z is an insulator.

Thank you atutor. Really appreciate your assitance. My son does have about 3 errors still - but it is a far cry from 12. Even though some of the answers in the key I was sure was wrong - wanted external confirmation. Thanks.

28 - I agree. I have always wondered about such energy conversion qs.

Hi All,


There is 1 missing page (last page) for Q44 from 2011 Rosyth Sch P6 Prelim Science paper in the latest package of the 2011 Prelim papers (Nanyang+Rosyth) supplied by Jeremy. Went back to check with the auntie at her stall and found out that those that she was selling also did not have this last page for Q44. In the answer key, there was answer given for Q44:
