thanks, so u r saying that if I take the x 0.75 formula using myresult/400, the actual psle score can differ byy at most 10m? :)tnx

I meant even if you use the calculator from the website that I have posted previously.. still have to plus/minus 10 from there.

Using your formula of result/400, will not provide any meaningful PSLE T-Score.

but the calculator cannot be used as the Sd and mean r not known... may be missing out on soemething... sorry to interrupt

yes.. have to know the SD and Mean...

If you have the mean, you can still use the \"standard deviation\" provide in the website. But then..if you don't even have the mean, it is really not possible to calculate the PSLE T-Score..

Can try using the mean and standard deviation provided in this thread.

Anyway, using the "mean" and "SD" from the other thread


PSLE t-score will be 248 (Set 1) and 240 (Set 2) for your posted result.

Let us know whether it is accurate after you received your PSLE score.

This is only a rough estimation based on limited information.

thanks as always, which schools sd and mean is this from? because the mean and sd will differ in psle as the difficulty is different from the sch prelims, ty anyway....


so my aggregate will be between 240 and 250 correct?
tnx :udaman:

I am not too sure which school as well. Guess you need to ask the poster from the other thread.

[KSP]

my guess for your T-Score would be


Set 1. 255
Set 2. 245

thanks a lot for the estimation KSP! :goodpost:

[KSP]

let us know when your results is out…

it is impossible to even get a close estimate for your prelim score… i believe ur sch teacher also uses the 3/4 x your total prelim score to give u an estimate…


whatever the mean and sd u get from any website, they are giving u based on past yrs data, not this yr… u wun know how well u fare as it all depends on the national standard of this yr students, though many say it is close as the results dun differ a lot but again, the difficulty level of the paper does play an impt role to determine the sd and mean.

with so many unknown factors, u cant get a close estimate at all, not to say even u have +/- 10 or more…

u wun know what is the actual mean and sd until after the results are released… till then, u already know ur actual results so there is no need for estimation anymore…
