Paper 1 was fine, albeit tricky. I found the Math paper 2 quite challenging, didn't have much time to check as I only finished a few minutes before time was up. I already lost marks because of the speed question ( careless ) and Q18 ( did wrongly ). My Math has always been my best subject, so I'm actually quite afraid now that I already scored this badly.

Tough questions ( Paper 2 ) : Q18, Q17, Q16

I'm not very sure of my answer for the folded angle question. Anyone can remember the answer? Please type out the steps too if possible, thank you!

Thank you for the quick reply. ^^
For Q6, I remember vaguely that my answer was 900 ml.
She drank 50 ml of water each day.

Also, at the end of the 12th day, 2/3 of the water was left and not 1/3.

Most of my classmates ( including myself ) put 32 degrees as the answer.

Thanks.
Thinking back, I think the answer should be 32 degrees too. I put 38 though, silly me. xD
