some one should do a statistics on this!

my understanding is also 220 need 4As.

my husband is different cohort as me, but he got 3As plus 1A* donkey years ago, but lower aggregate score than my 4As.

This is highly possible because the mark range for A is very wide - 75-90 marks. This is still happening today.

I do not think MOE revealed the average score for each subject in the past. So wonder how to do statistics.

Without average score and standard deviation, based on that T score formula, we only know that a student who scores the average score for all the four subjects will get a T score of 200.

Can we make a guess of what mark range will the average be?

if bell curve is consistent, the value of our stars last time is it the same as now?
does my question make ssense?

agree about the big range. my friend's 4As is worth 12points more than mine.

A boy who just did PSLE last year had 208…3 As and 1 C.

So I feel that to get 220, child needs 4As.

[Nebbermind]

U have to compare the psle results with the kid’s school performance to figure out how much a grade is worth.


I know of one who always got high C or low B for Chinese in school and finally got an A for psle. That wld more of less mean that the A is a very low A.

If the diff between a low A and low a* is roughly 10 pts or 40 over four subjs.

The following information can shed some light:

1. If a child scores an average mark for all subjects (i.e. if he is at 50 percentile for each subject), his T-score will be 200.
2. At national level, students scoring A and A* (2011):
English: 44.3%
Maths: 43.5%
Science: 43.5%
Chinese: 80.6%

Hence, it is possible to require 4As for a T-score of 220. Of course, since the range for A is so wide, a child with 4As may also have a much higher T-score than 220.

I am not trying to scare anyone here.


If a student gets average score for all the 4 subjects, his/her T-score will be exactly 200. If the average of 4 subjects is 75% (which I doubt for some subjects like Maths), then one really needs 4A to get a T score of 200!

I dont think the national average for any subject will be 75%.
