Selecting a secondary school and PSLE results

Just submitted via the S1 system the following schools for my younger daughter.

Choice of Secondary Schools
1st :3005 - Crescent Girls' School
2nd :3013 - Tanjong Katong Girls' School
3rd :3512 - Tanjong Katong Secondary School
4th :7021 - St. Margaret's Secondary School
5th :7023 - CHIJ St Theresa's Convent
6th :3029 - Clementi Town Secondary School

Pity she had a B in CL to accompany her three A*s. 81% of  her cohort achieved A and better. You can imagine that her T-score for CL is way below 50.

The top pupil achieved 282. Typically that would be the perfect score. Assuming that the outcomes for all the four subjects are similar, the likely maximum T-score per subject is 70. See this blog for and excellent lowdown on t-score calculations.

A very crude estimate as we do not have any clue about the mean and especially SD for each subject, the T-scores from her A*s should range between 190 to 210. Therefore if CL wasn't an issue and she was just average of her cohort, her T-score is easily beyond 250.
