Hi dyh,

Thank you so much. I think you have solved the mystery. There are many identical scores and based on the scenario i have posted earlier, the 4th student with 93% is likely to be ranked 3rd not 4th. Am I right? So although there are top 50 positions, there are more than 50 students filling the positions, affecting the percentile accordingly.
Thank you so much for yr explanation. I have been trying to figure out why.

Haha, with all the posts trying to figure out on the percentile, I have hit 1000 posts... haha :rahrah: And now I am a KiasuGrandmaster... LOL.. :rotflmao:

Assuming the lowest percentile for getting credit in this round is 85 % ( this is only assumption hor), then no of students taking this exam shd be 800… Since 120th position rep top 85%. This is quite possible as we do not expect all p5 students taking this… Most likely all the geppers and the top mainstream classes. So I think 800 to 1000 total intake is fairly reasonable.

But if dyh knows of a child who is in the 98 percentile but not in the top 30 list, then the sample size cannot be 1000.

Hi, It is possible to have all the kids from percentile 85% to 98% to be ranked between 51 and 120 if many have identical raw scores.

Hi dyh,

May I know whether the child who scored 98 percentile gets to the second round. I think the list of top scorers may not be the top 30 positions. It may be the top 5 positions taken up by 30s pupils due to identical score. So if the rule is students who are in the top 50 positions get into the second round, then that child has high chance of getting in. Maybe the child shld check with the teacher.

Hi, according to my ds, 2 or 3 people got above 98 percentile but no second round invitation.

Thanks for yr response. Maybe the students assume that their name are not in the top scocer list and hence not selected for the second round. The tr shld know who go into the second round. I think the best is to check with the tr.

http://contests.heymath.com/admin/RI13#. If you click on contest, it is written top 50 in round 1 are invited to the round 2. However if you click on about the contest, it says top 30. If top 50 are invited, it cannot be only pupils in the list.


It is written all students on the top scorers list will be invited to round 2. Dont think it is written only pupils in the list are invited into round 2. I find the information confusing till you bring in the possibility of identical scores. Thanks. Anyway I will try to check with the trs on Monday.

..dropping by.. from what I know/gather..

for Round 1 (RIPMWC), Certificate of Distinction is awarded to the top 50 scores... for those who get into Round 2 (top 30 scores), they will earn the Certificate of Higher Distinction if they are among the top 15.

The percentile figure provides an indication of the number of participants, rather that the score. So, if there are more participants, you can expect the \"cut off \" percentile for the top 30 scores to be higher, and vice versa.

From what I know, the max number of participants for open cat (P6) this year should be around 3160-3170... I know of student who got into Round 2 with a 98.8 percentile and another who did not get into Round 2 with a 98.6 percentile.

cheers.
