Hi Verysuperkiasu


My answers for the 3 questions are the share as your son's.

Thank you so much, atutor! It's comforting to know that u agree with my son's answers. When I first marked his papers, I freaked out to find that he has five wrong answers coz that meant A* gone. But I've never come across so many wrongs in the answer keys though.

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.
