HELP: Psle score rough gauges

[kiasu.023284.023284]

KiausuLormee:

Is it true that we just plus 10++ above marks in prelim score, we can roughly know how much will be in PSLE T-score.

how is that possible? the difficulty level, and your marks will differ greatly in PSLE

kiasu学生:

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.

KSP:

if we don't know the Standard Deviation and Mean we can't calculate the the T-Score correctly too.....

Yes.

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..

[lynntan15]

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
