For previous years' cut off points to special round, please refer to an old blog post here.
Is this year harder than last year?
ReplyDeleteWhat do you approximate the cut off point to be?
Qn35 only has n=2015, 180
ReplyDeleteWhat do you think the cut-off point would be for bronze?
ReplyDeleteQuestion 16:
ReplyDeleteAP = either 27 or 29
27 + 29 = 56
Can anyone clarify this thanks.
No, AP is either 25 or 26.
DeleteFirst, note that triangles ADQ and AQP are similar such that DQ/QA=AQ/AP and hence AQ^2=DQ*AP.
Next, AD^2 + DQ^2 = AQ^2 = DQ*AP such that 12^2+DQ^2=DQ(34-DQ), yielding DQ=8 or 9 and hence AP = 25 or 26
What is this year's cut off for round 2?
ReplyDeleteWhy is question 8 ans 5?
ReplyDeleteSorry question 18
ReplyDeleteWhat do you think is the cut-off point for Bronze. Is about 10 points enough?
ReplyDeleteBased on past years result 10 points in enough for Bronze I am wondering whats the cop for hon mention though
ReplyDeleteWhat's the estimated minimum for bronze?
ReplyDeleteDo you find the difficulty of the paper to be similar, easier, or tougher compared to other years?

ReplyDeleteHi Hantao, the initial answers are provided by a student fr NUSH. I will ask Lim Jeck or Lim Li to check the answer for Q18. Thanks.
ReplyDeleteLim Jeck has confirmed answer for q18 to be 4. It is amended. Thanks Hantao.
ReplyDeleteThank you! ☺
ReplyDeleteare all the answers here correct?do your think this paper is easier or tougher than previous years?
ReplyDeletehi, anyone knows when the results are out ? thanks
ReplyDeleteHi, dont think the cutoff is so high cos my friend and i got 15 and we both got into round 2.
ReplyDelete15 for junior can get in ? I feel this year harder than last year.
ReplyDeleteI got around 16, but still got into round 2, so I don't think the cut-off is that high
ReplyDeleteAnyone knows how to do question 4? The question is on tourist.
ReplyDeleteYou got to realise (and prove) that if there are n tourists, the minimum would be (n - 7) tourists. Since the minimum number of tourists is 10, the minimum would thus be 10 - 7 = 3.
DeleteJust consider when n = 10 to 13, there is a way to get 3 tourists only.
ReplyDeleteHow's round 2? How many questions can you do ?
ReplyDeleteAre the round 2 results out yet?
ReplyDeleteAny idea when results will be out?
