I got confused with all the mean(average) and median UAS.

Median UAS is the UAS at the 50th percentile and mean is the average UAS.

Based on historical data, is median UAS usually higher than mean UAS?

So RI mean UAS is 84.5.
NYJC median or mean UAS is 85.X?

Then NJC median UAS is 84.4, so what is its mean UAS?

You are right. median is usually higher than mean based on historical data. NYJC median is probably around 85 since they said 50% of their students attained more than 85 UAS. So, at 50 percentile, it stands right at 85.

NJC median UAS is 84.4. Mean should be lower than that, usually 1-3 points lower. these number is quite credible as NYJC cop in recent years is 7 while NJC is 8. So, njc attaining slightly lower result is about right.

yup more than 50% NYJCians scored 85 RP and above, meaning that the median is definitely higher than 85RP.

NYJC and NJC have the exact same COP for both Science and Arts for year 2017 (2018 A Level Results),

Science: 6
Arts: 7

So, NJC attaining slightly lower results is not \"about right\"[/quote]I got the above cop from a website, probably a discrepancy, that website is showing 2018 data. You are right about the \"not about right\", come to think about it because NJC still has its IP cohort which usually has a rather high COP.

So who is now number 3, after RI/HCI?

My office colleagues said NYJC.
4th place is DHS? NJC? VJC?

Nanyang Junior College ony take in JAE students, 2017 JC1 students, for 2018 A-level.

In contrast, if we were to flashback to PSLE 2012 batch, those P6 students who entered National Junior College, their IP Cut-off point back then, was around 257 for NJC, and was quite a large pool of IP students. Therefore, it is natural to expect National JC to perform better than Nanyang JC, at 2018 A-level

What is the cohort size of NYJC?

Correction: NJC IP is a small cohort, not “quite a large pool”. It is only about 190 + students. The majority of NJC JC students are actually from JAE (probably about 2/3 or more).

NYJC P said >40% got 3 H2 As, I would assume it would be anywhere between 40.x% - 43.x% otherwise he might have called it “almost 50%” NJC said about 1 in 2 got 3 H2 As, using the “new” formula for rounding up, I would presume NJC % of 3 H2 As would be somewhere between 44.x% - 53.x% , so better than NYJC in this aspect?

So taking all these into considerations without knowing more information, it’s hard to tell who exactly performed better than the other...

I thought we know the median UAS for both JCs?

NYJC median UAS around 85 or slightly higher.
NJC median UAS is 84.4 as they released.

Like what floppy shared, people are number crunchers and we love to slice, dice, and analyse what caused that x% improvement from this JC over the other. However one factor we often overlooked is the attrition rate. In RI’s case, the intake should be 1,200 and last yr 1,190 took the As - an attrition rate of less than 1% which is very lenient for a top-tier sch (other sch may be equally humane, I’m not saying that they are not, just that I have no knowledge of other sch stats).


This pt resonates with me bcoz this yr during town hall, the sch’s mgt shared that they do not want students to be unduely stressed by grades. Thus, they are going to lower the promotion criteria even further by removing some mandatory conditions and lowering others. So I think this ‘less than 1% attrition rate’ is here to stay, and will get even more lenient in years to come. By doing so, the sch is trying to give as many students a chance to progress as they possibly can. So while the sch is naturally proud of its stellar records at the top end of the bar, it will also accept the less than perfect records at the other end of the spectrum (2% without 3 H2 passes + pass in GP or KI) if the bigger objective of giving as many students a shot at the As is met.

The sch has made its decision, and it’s not crunching stellar numbers at all costs. If some of its graduates are going to be our future leaders, I think there are valuable lessons to be learned here.

Exactly, This one better than That one in XXX, but That one is better than This one in YYY, so how?

I don't know abt the other JCs. Only RIJC's.

Thanks nn. With this new version of the forum, I don't seem able to logout - forever trapped in an eternal cycle of clicks. Lol
