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

atutor2001:
Hi actor2001No special formula. My computation is based on raw score x 0.712.
The magic figure of 0.712 was derived from those years of sleepless nights, trying to figure out what my kids T-score would be and it is pretty accurate and consistent for a \"normal\" PSLE i.e. without killer paper.
If there is a killer paper and the student does well for that paper, his T-scope will be higher than that computed using 0.712. (the increment is more if you get A* for the killer paper). The reverse is true. The subjects that affect the T-score most are Chinese and Math so die die must do well.
:goodpost:
Your formula is user friendly and we at least can learn how to estimate for our children.
Noted your comments and that why's I am very concern over the quality of the CL compo. as well as the CL Oral.
Thank you. -

Haha, i tot i was the only one wasting DD time in speculating about the intricacies of T-Score, with all the ifs and suppose and what ifs.

Hi verykiasu2010
Sorry read your earlier post wrongly mistaken normal A* to be normal A.
let say high A* is 99 and normal A* is 93 then my bluff is T-score about 273
Is there anywhere you can get the national mean score for each subject -past years?
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: -

that causes some panic to some parents now ...[/quote]Once you score a B in any subject your chances of scoring more than low 240 is very slim.
Too bad he did not have DSA. I heard some GEP students were caught this way too, getting 240+ and no DSA.phankao:

Eg, last year one of my student scored 3 A* for EMS but he got B for MT, aggregate 240 go to neighborhood school. -

My two friends' son and daughter both got 4A each and their t-score were 238 and 239 respectively in last year.
last year, one of my gal's classmate scored 4 As
intially, her mum when heard her \"4 A\" was very happy.....
but later realised that the T-score was only 22X -
btw atutor,
I have read ur posts before about t-score. At that point never understood what you meant by low score in maths /Chinese can pull t-score down a lot.
Only when i palyed around with scores, SDs and means i realised how true ur conclusions were . So Thanks U.
Maths today- waaaaaaa, cant bear the tension. -

:shock: . 4A could be 238-239 and also could be 22X...., different almost 10 marks.Brenda10:

Oh dear. :([/quote]oh dear, it makes us nervous, our kids are having their exams now and we are already guessing their T-scores. Can't imagine when the day comes when the results are releasedAugmum:

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

seems like there is a correlation between CL & MA
but bear in mind the 0.712 is an observation only, an estimate
every year the mean and SD for every subject fluctuates within certain range
