Try this website but you need some basic data like Standard Deviation and Mean for each subject.

thanks for the help lynntan15 , but to calculate the psle agregate or TSCORE the standard deviation and mean is not known and i dont think it will ever be. but do you know how accurate taking the total/400 x0.75 is, as in, how many marks can your real scr differ by. many thianks.

Hi,

It is a misconception that the maximum aggregate is 300 (Total ÷ 400 X 0.75). In fact, there is no such thing as a maximum aggregate. You can go to this website which provides a full explanation of how the PSLE T-Score is calculated with examples:

Without the mean score, the T-score will never be accurate nor anywhere nearby.

The main indicator is still the mean and how much you deviate from the mean, will determine your PSLE T-Score.

You should be able to get the mean and SD from the report book.

Even so, the PSLE T-Score will still be plus/minus 10 point.. from what i observe.

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

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.

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

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