What's the cut off point for bronze this year?
ReplyDeleteWhat will 15 get me? The general consensus amongst my classmates is that this year is easier than last years, and last year was 16 for cut off for round 2
ReplyDelete15 should be eligible for r2 minimum silver
Deletelast year was easier imo
DeleteI think q8 is 60,
ReplyDeletex=35 and y=12.5
That is the case where x < y. But the solution gives x > y. So you have to reject that solution.
Deleteyep got same ans too for y>x
DeleteDamn made the same mistake
DeleteX cant be 35 it does not yield 70 for first part
ReplyDeleteWhat is the cut off for silver this year?
ReplyDeleteI'm guessing 13
DeleteJust curious what are some of ur scores?
ReplyDeletehow can q15 be 82
ReplyDeleteCos when x is 8 m is 82/9 so 9m is 82
ReplyDeleteq13 i subbed P(1) which yields 1024 but why must u multiply by half?
ReplyDeletemy guess
ReplyDeleteHM:6/7
Bronze:11/12
Silver:13/14
Gold:18/19
R2:15
hello, newbie here. how does r2 results affect the award received?
DeleteFor the final award received, I think r1 and r2 results are added together, so getting a high score in r1 won't guarantee a gold, and getting lower score in r1 can also give you a gold
DeleteI see, thanks!
DeleteWhat are top 30 scores?
ReplyDeletehow is 3028 the max for q20
ReplyDeleteYou use the sequence (1,-2,1,-2,...,-2) giving a sum of -1009. 2019-(-1009)=3028. To my knowledge, this is optimal.
ReplyDeleteWhat about the sequence (4,-5,-2,1,...,-2,0)
ReplyDeleteWhat will 13 get me?
ReplyDeletehey same i got 13
DeleteNevermind I am careless
ReplyDeleteIs 18/25 a decent score?
ReplyDeleteI'm quite concerned because quite a lot of people did better than me.
what do u think the r2 cut off will be?
DeleteCan 15 get me to the 2nd round
ReplyDeleteWill I get gold with 5? Most of my friends got 2
ReplyDeleteSure
Deletenot to burst your bubble of hope but a 5 is not GOLD, it is guaranteed SILVER
Deletemy take;
hm: 2
bronze: 3
silver: 4
gold: 7
round 2: 4
PLS LA not that hard one
Deletehm: 0.2
bronze: 1.25
silver: 3.1415926
gold: 4.333333333
isnt q8 supposed to be 60?
ReplyDeleteWhat will a score of 6/25 get me haha
ReplyDeleteThe Most Honourable Certificate of Participation
Deletehow do q 16
ReplyDeleteAny nice explanation for q20 my friends and i all guessed
ReplyDeleteWhat can I get with 13
ReplyDeleteI got 17, carelessly got qn1 wrong hehe, i feel this year's paper easier than 2018's since i only got 12 for that one...
ReplyDeleteBtw when will rnd 2 name list be released ahhh, uncertainty..
Can 17 secure a silver??
I got 21 for 2018 and 13 for 2019 feels bad
Deleteim back wins gold hehe
DeleteDid result come out?
DeleteYes results are out to schools
DeleteQuestion 6 is 99997.
ReplyDelete@Unknown You can test that; it isn't a factor.
ReplyDeleteIsnt q21 265 instead of 268?
ReplyDeletewrite numbers like this:
ReplyDelete1 4 7 10 13 ...
-2 -5 -8 -11 -14 ...
if x_(n-1) is in the top row, next term is either to its right or below it. if it's in the bottom row, next term is either to its left or above it. this means that each negative number will always have a positive number to pair with, so the max is 2019-(-1)*1009=3028
My guess:
ReplyDeleteHM: 5-7
Bronze:8-10
Silver:11+
R2: 16
The difference between silver and round 2 cant be that much. Most of silver will be for those who went round 2.
DeleteMy guess:
ReplyDeleteHM 6-7
Bronze 9-10
Silver 12-14
Round 2 14-15
My guess:
ReplyDeleteHM 8-9
Bronze 10-12
Silver 13+
Round 2 14
Can someone explain Q18?
ReplyDeleteLet a = log2(x) and b = log2(log3(y))
DeleteGuys mind sharing how much yall got?
ReplyDeleteI got 15 and I got in.
COP should be lower than last year
I got 14 and I got in lol
ReplyDeleteWill I get silver with 13
ReplyDeleteGuys help how much do we need to get in round 2 to get gold?
ReplyDeleteThis comment has been removed by the author.
ReplyDeleteno. 23...my answer is 1009.
ReplyDeleteWrong the answer is 2019
ReplyDeletehow to do q13
ReplyDeleteWhat is the cut off for silver???
ReplyDeleteDefinitely 12 based on previous years where cut off for silver is 2 marks less than round 2 cutoff
ReplyDeleteWhy I even thought 2009-2011 was easy
ReplyDeleteI could answer 16 for 2011 but only 13 for this year
Why does the answer q13 is 512?
ReplyDeletegot 20 but didn't get R2... strange this yr has high cutoff.
ReplyDeleteFor Q13, you substitute x=1 to get P(1)=1024, and P(1) is the sum of all the coefficients (both the even and the odd powers of x). Then you substitute P(-1) and get 0, and P(-1) is the sum of the even powers of x coefficients - the sum of the odd powers of x coefficients, since (-1)^even power = 1 and (-1)^odd power = -1. So the sum of the even powers coefficients - the sum of the odd powers coefficients = 0 and the sum of the even powers coefficients + the sum of the odd powers coefficients = 1024. Solving these simultaneously gives the sum of the odd powers coefficients and the sum of the even powers coefficients are both equal to 512, and the answer is the sum of the odd powers coefficients, i.e. 512.
ReplyDeleteCan upload round 2 questions?
ReplyDeleteThoughts on this year paper? Felt q1 (geometry problem) was manageable, q2 idk what it was about, q3 was fairly easy but i am not sure if i proved fully, q4 was a scam, q5 was quite easy( ans is multiple of 2)?
ReplyDeletewhen will the final result be released anybody knows tks
ReplyDeleteProbably end of July just like last year
DeleteHow to get 32 for q6？
ReplyDeleteTry expressing it as ax²+bx+c+d/(x+8)
DeleteI DO NOT BELIEVE Q15 IS 50 i could just take 99+97 and leave it there and it will be done with.
