Hi , my son says that the pattern is as follows :


1 ---------------------12(rods needed to make a cube)
2 ------------------- 20
3 ------------------- 28
4 ------------------- 33
5 -------------------- 41
6 -------------------- 46

Thanks,
Yes, I got the first number in the series wrong, regardless of which the answer is 782.

Yes, based on my visualization of the structure, item 3 should be 28, thereby the CORRECT answer to Q17c is indeed 782.

I am utterly impressed with the kids nowadays, they can summarise almost the whole exam papers a few hours after taking it, :celebrate:

This boy JianRong and his friends deserves a pat on their back.

However, the relatively Maths paper is a little unkind to those who excel, as there were NO real difficult questions. DS said he was only able to use algebra once and it was a giveaway ( Q18 ). We should see a lot of A* this year.

Agreed with MOE Hater, the paper should have a few tough questions, as in 2009.

I sincerely believe this year's P6 cohort is one of the best academically in recent years, though the PSLE Tscore may not reflect so ultimately, due to the relatively easy papers so far for English, maths and Chinese. Easy papers raised the Median Score and affects the Standard Deviation substantially.

Jiayu to all

i got 46

, 9cm, 180cm, and 782 for the 2nd last qn.

an somebody tell me if that is confirm correct or not?

Jiayu to all [/quote]i agree. better more difficult paper so good pupils can show more potential.
heard that they qoing to raise the A star so not many pupils get A star for math.

All right. lucky u :celebrate:

\"easy paper means lower T score..some parents pray for difficult paper\". Is this true? Heard from expert parents.

if you can get 100/100, how to get low t-score?

In T-score computing, the 'mean' and the SD (Std Deviation) are the key-factors. If so many students score 100/100 or A*, then both 'mean' and 'SD' will be unusually high. In that case, the T-score will be lower.

Innocent students rejoice at the easy Maths paper since their raw scores will be higher. Unfortunately, since T-scores will be lower, I feel there is not much justification for the rejoicing. Finally, it is the T-score that really matters. Is it not?

What about the COPs of schools? Will they go down too compared to last year?

When the mean is high, the standard deviation is usually lower than a difficult paper. So the marks are somewhat moderated, there no need to be so overly concerned

MOE did satiisfy parentrs but it did not satisfy the top students who excel…

for an easy Maths paper is def lower compared to a diffcult one,
as the mean score and the number of perfect scores pupils are def raise.

just like last year, i can cautiously said that the difficult maths paper
did contribute to a a higher T-score as seen for my gal's case and some of them whom i know.......
on the other hand, it did pull down those who did Very Badly for that Maths paper,
as some of them had gotten a T-score of abt 10 points below expectations,
resulted in not able to get into their choice of schools.
