What is lowest PSLE aggregate you can score with 4A*?

[Animalfarm]

I agree that the aggregate is more important than the A’s. My Daughter got 3A’s and A* for MT and her score was 253. Her friend got the reverse, 3A* and an A for MT and her score was 255.

the mean for math and CL are usually higher than Sci and EL, and SD is smaller than Sci & EL

How do you know this?

seems like there is a correlation between CL & MA

Came across a report that about 10% of the student population are \"foreigners\", PR...

These students are so good in CL and MA that getting 100 is chicken. For MA they are ahead of local students by at least 1 year in terms of coverage and yet they usually join a class that is younger than them by 1 year - so that they can catch up in EL. No need to comment about CL.

With additional foreign students scoring A* (on top of our own local A*), we can guess what will happen to the \"mean\" and our T-score if we don't do well in CL or MA. I guess that was why the proposal to give less weightage to CL was made. Unfortunately many don't understand the good intention and made lots of noise.

I agree. My dd's had China classmates who exceled in both Chinese and Math so scoring full marks or near full marks for them was a regular occurence. Unfortunately, not all locals who score full marks for Math are as good in Chinese, even struggling for some.

This is definately correct. The range for A is rather wide and it is impt to meet the highend of A in order to get a good T-score.

I know a boy who has a grade profile of 2 A* 2A with a T-score of 268.


He was a former classmate of my son. The boy is now in his fifth year at HCI.

My nephew got 4 A* and T-score of 270 last year.

they should learn to face the competition rather than we changing the rules to help us score, the world out there is a real world

sorry wrong info, saw the wrong columns, (small group only)

kindly please ignore

My thesis :lol: makes me feel that the constant (0.712) will vary for the ranges. ie it will be higher if a person scored all A* s. etc. and

By your logis for one who scores 100 in each subject, will get only 285 as T-score :shock:

Hi Sun_2010

You are absolutely correct that the constant will vary with the range. 0.712 is applicable for scores of A & A*. The constant will be lower for scores in the B & C range.

Just to share how a more accurate constant can be estimated for each subject.


Lets say the mean = 71 marks
The constant for a score of 71 (mean) = 50/71 = 0.704
The constant for marks less than 71 will be less than 0.704, (the lesser the mark, the smaller will be the constant)
The constant for marks more than 71 will be more than 0.704, (the higher the mark, the bigger will be the constant). However, from my observation, the highest constant is about 0.72 (dependent on the SD - the smaller the SD the greater will be the increase)

Therefore, by estimating the mean score of each paper, we can roughly estimate the constant to use to get the T-score.

If the paper is easy, the constant at the mean will be smaller but will increase more because of the smaller SD - the upper limit is about 0.712.

If the paper is difficult, the constant at the mean will be bigger but will increase less because of the bigger SD - the upper limit is about 0.72.

PS

My earlier description was wrong. The changes are in red.

I heard some GEP students were caught this way too, getting 240+ and no DSA.

that causes some panic to some parents now ...

They were the few GEP students that just didn't successfully get any DSA offers. And yes, my friend said the parents were very sad on the results day. ;(
