[ssll]

Anyone knows, appeal shd be done now for our choice of school or wait till the posting results is out then appeal ?

[Advisepls]

Hi all


I got 255+2(HCL) for PSLE. I was asked to try for Dunman High since i'm only one mark away. COP is 258. However, i am contemplating whether to choose Cedar over Dunman since i have a feeling i would do better there. I'm not that bad in chinese but i'm not extremely good either. which school would you advise me to put as my first choice?????????? :?: :?: :?: :?: :?:
My goodness。I am only left with a few days to decide. SOS

You have no grounds for appealing with respect to choice of school unless you have already been posted to a school which is not the school you wanted.

ahque:

as he had fever during psle, with special consideration of 4 points, he has 232. goin to appeal for sst as our ds didnt manage to clear e 2nd around. now, we are struggling as to which schools to choose. seems like to risky to put sji as 1st choice, but we can only appeal if we put sji as 1st choice rite? our choices :-

1st choice - sji
2nd choice - maris stella
3rd choice - clementi town
4th choice - ?
5th choice - ?
6th choice - ?

:?: :?: :?: pls advise.

I think appealing for SJI through normal channel is difficult because the COP is 241. Therefore, there is no real advantage in putting it as the 1st choice.

My personal consideration for Sec school is discipline and distance. I think Maris stella is a good choice. Maybe you would also like to consider Nan Chiau (231) and Presbyterian High (229). The 4th, 5th ... choices are not important if we are realistic with our first 3 choices.

Any comments on Serangoon Garden Sec?? in terms of their discipline, students’ behaviour…& is it conducive+nurturing environment??

What about Guang Yang & Pierce??
Thanks in advance!!

[JonC]

Err… it Peirce.


Though not banded, some parents and teachers of DS school have good comment about the school. It may be an up and coming school.

[cool_hi]

Hi JonC,

Thanks a lot for the reassurance…tink I will tell my friend to put as 1st choice then…but chances may be low, coz their COP is betw 206-208…so 203, really quite slim chance…
What about Serangoon Garden Sec(it’s the nearest, so very tempting!!),
Guang Yang, CHong Boon & Yio Chu Kang?? Anyone has valuable advice/comments?? Thanks in advance!!

every school's raw score is of no help in the estimate because their standards are different from school to school. A child from school A with raw score of 380 cannot be compared with another child of the same raw score from school B.

I am using PSLE score here to estimate - not raw score from schools.
[quote]And nobody actually know the raw scores in the actual PSLE exam, but it is a known fact that every subject's mean and SD are different

I am making informed guesses of the PSLE total raw-scores from the extreme cases. The estimate is for overall mean and SD. [b]Since the papers are easy, the SD should be quite consistent for all 4 papers[/b].
[quote]it will be more instructive if the schools provide its own t-score for every student every year and bench mark it to actual performance at PSLE and see where they stand. that will be much more able to predict the PSLE actual scores [/quote]

I know a NYP girl who failed her P6 math in every semester but got an A in PSLE, which explains why the mean for NYP math is ONLY 65.8. She was so demoralised and her parents were so upset. I really cannot understand how such mis-match between prelim and psle standard is of help. So the parents will tell the kid, \"Don't worry, it is ok to fail now. Based on the bench mark to actual performace at PSLE, you will get A\"

Therefore, knowing that the overall mean is around 69 and yet that school's mean for math is 65.8, we can tell the school that they are doing a disservice to the weaker students. Losing confidence and developing dislike for math is not something that can be corrected easily.[/quote]

you know the actual raw scores for the PSLE ? don't joke / mislead people lah

the papers were easy, BUT not all 4 subjects are all equally easy. what a joke to say there should be \"consistent\" since \"they are easy\". Consistent in what ? consistently different from each and every subject is more like it

why upset ? it just shows that that girl need some waking up to before the PSLE to achiever her potential

the school's overall result is proof that what they do is on the right track : more than 82% scored at least 4As or higher

in every school there are stories of pupil who scored badly in school tests and did well for the PSLE - waking up not too late from the slumber; there are also some proud peacock who did worse in PSLE than in prelim

parents should bear in mind that every subject's mean and SD is different from year to year

No, I don't professed to know the PSLE raw score. But just to explain how an \"informed\" estimate can be made :

(1) Top scorer 282 and 2nd is 279. The difference in the raw score is about (282-279)x4/3 = 4 marks. So it is a fair guess that the top student gets nearly perfect score i.e. 99 per subject (average)

(2) There is a known case of 263 with 4A* (the lowest known T-score in this forum for 4A*). Assuming that this is a case of getting exactly 91 for the A*, I worked out my first estimate of average mean = 64 and SD = 17

(3) Then a new case 3A* + 1A getting only 249 which would not tally with the earlier computed mean and SD. Re-estimated the 263 case to be with average of 92 marks and got new mean = 69 and SD = 15.

(4) Checks were made with other results and so far the estimate is fine.

Then there is this nagging question of how the differing SDs and means for different subjects will affect the accuracy whereby I am computing using information on the combined total and average.

T-score : T = 50 + 10/SD x (Raw - Mean)

If the SD ranges from 14 to 17, the factor 10/SD will range from 0.7 to 0.6 and the change is not great. Since the papers were easy and for the purpose of estimation, I assumed the SD to be constant. (cannot use NY's SD range because their math's SD is unusually high, 17+ as it is well known that their math paper is difficult)

Working with the T-score formula :

Total T-score = T1 + T2 + 73 + t4
Total T-score = 50x4 + 10/SD x [(R1+R2+R3+R4) - (M1 + M2 + M3 + M4)]

Average T-score = 50 + 10/SD x [(R1+R2+R3+R4)/4 - (M1 + M2 + M3 + M4)/4]

Note that :

(R1+R2+R3+R4)/4 = Average Raw Score
(M1 + M2 + M3 + M4)/4 = Average Mean

So Average T-score = 50 + 10/SD x (Average Raw score - Average Mean)

Therefore, through \"informed\" guess of the Total Raw Score ie. using cases of highest T-score and lowest T-scores for certain combination of grades, I can estimate the Average Raw Score and then work out the estimated Average Mean and \"assumed\" SD.

Hope this explanation will give a better idea of how the estimates are done. No intention to mislead anybody.

My next self-question is \"What is the use of such estimation?\"

It has been bugging me since my kids' time as to what is the \"mean\" in the actual PSLE. Through this estimation, I am now clearer that for \"normal\" PSLE papers, the mean is around 70. That means, a child must achieve an average of 70 marks to \"pass\" for Sec Express. I can also re-distribute the average mean to different subjects based on \"experience\" example, Math will be more than 70 about 75, Science will be about 65....)

Then how is this useful, as papers changed over the years. To me, as long as the paper is normal, the mean will be around 70 and the SD around 15. If the paper is difficult, the mean will go below 70 and the SD up to 18 (as show in NY's info for math paper)

Sad that you take these estimates as misleading. Please just ignore them. For others who find them so, please also ignore my postings. Will make myself scare in future.
