how do u get the ans for q25

how is q25 1009

Considering x terms,

1 - (1-x) + (1-x)^2 - (1-x)^3 + (1-x)^4 - ... - (1-x)^2017

= x - 2x + 3x - 4x + ... + 2015x - 2016x + 2017x + ...

Coefficient of x

= 1 - 2 + 3 - 4 + ... + 2015 - 2016 + 2017

= 1008(-1) + 2017

= 1009

Why is there 25 qns this year?

Any idea what may be the cut off score this year?

Why is 54 the answer for question 11?

somebody say, cut off : 12--13

Is 16 enough for gold?

This year's paper is much more easier, which includes many primary school questions. Personally I think. And the format changed

The format had changed

how many questions must we get correct for bronze/silver/gold

How much do you think we'll need to get gold?

I got 20 out of 25 for the first round but then my coach said i might not make the second round.

yes, much easier and longer time for each try. 21 as cut off point will not be surprise.

Some questions were doable, some were hard

thanks yall for making me look like an idiot :') i probably got like 6

Is 10 enough for honourable mention?

Guys I need your help. Is 16 to 17 enuf for silver?

Will they be more lenient in this time’s grading system? Coz I think there are fewer choices of questions to choose from, which means that the paper is more difficult the scope is narrower.

Guys what rank is 15???

Hi guys, is 16 enough for Round 2/ Gold?

Everyone who goes to round 2 is guaranteed silver, and in order to get gold you must get into round 2 and do well in it I think.

Wait if we can get 15 can we get into the second round. My friend said the cut-off should be about 10-15, but I am not sure. How am I supposed to know?

Guys I got like 6 will that get me into round 2? I really want top 30

I think that is participation tbh

Is 20 enough for round 2??

Will 10 get me a silver? I want to get into 2nd round badly...

Is 12 enough for a bronze?

I would estimate the round 2 cut-off to be around 17-18 probably

@anon who got 6 yeah u round 2 and gold.

What'll be the cutoff point for this year? I got 21/25...not sure if that's enough...I know people who got 24...

How do u get ans for q12?

This years paper was very easy. I checked my answers and I think that I got 25/25

What is the total mark required to get top 30 ... special round seems very difficult

Will 15 get me a sliver?I really want to get top 30

I checked my answers and I think that I got 15/25. Is it enough for a bronze?

I got around 12 correct.. would that get me at least a bronze?

Is 20 enough for round 2? Primary 6 here.

Q12 is not 5200.Let the total number of phone is p.

We have: 1800=200*(p-2)-m/p

=>1800=200p-400-m/p

=>2200=200p-m/p

=>p>=2200/200=11

In other way, m is smallest so p is also smallest.

If p=11 => we have: 2200=2200-m/11

=>0=0-m/11

=>m=0

But m cannot be 0 so species

If p=12 => we have: 2200=2400-m/12

=>0=200-m/12

=>m/12=200

=>m=2400

Thus the smallest value of m is 2400

p is a prime

is ten enough for a award?

what will 14 get me?

14 will get you bronze to silver. Likely bronze.

Can anybody help me with qn 18 ? Its pretty confusing

News!! SMO ROUND 2 RESULT CAME OUT!! CHECK EMAIL AND WITH YOUR RESPECTIVE SCHOOLS!!! I got 20/25 and got in round 2!! Can someone say how much they get so we know the COP?

Hello, are the round 2 namelist out online already?

If so, can you send me the link to the name list?

Cutoff should be about 15. Anyone getting below 15 and got into round 2?

16/25 here.... chances of getting into R2? I understand I'm treading on a tightrope (between getting and not getting into R2) here....

Have yet to receive email although nobody I know has, even those with >18 questions correct... is there perhaps a namelist you can share?

i have got the list of 2nd round participant, it is given via email. i can try to find your name if you give your initial name. only 230 names on my list

Is it ok to just send the list so everyone can check themselves?

hey justyn, what were you wrote before? haha, congrats btw! how many questions you got right?

Are there any Chung Cheng High Main winners?

Yes, only one. entry number 18 : Young Y H

@ Justyn, for question number 18, just make a line from D to C, after that you can solve it using area of triangle. -Hd

Will the list of round 2 participants be posted here?

R2 list for your reference (I suppose there are no inaccuracies)

Cutoff this year should have been 16 - I'm the 16/25 boy (refer to comment on 11 June at 2203) and I know people with 15/25 who are not in R2

Any idea how many people participated? I wanna know what is the percentage cutoff for round 2 participants.

Top 10% in R2 so ~2300 ppl
