[quote=\"2CentsWorth\"]Hi, after reading through all the answers that are being shared, I just want to clarify a few answers:
Black & white tiles qn : answer is 180 metre sq (area of black tiles)
Another qn (not sure qn no.) : 4576 (NOT 4567)
Nope, I'm a mother taking the PSLE with her son :roll:[/quote]

yes! Jia You! :rahrah: -
With regards to the black tiles question, if each tile is shaded 5/9, Then when repeated, the fraction will remain the same. Thus, regardless of the number of tiles, the fraction of black tiles in total remains as 5/9. Therefore the area of the black tiles in total will be the total floor area multiplied by 5/9

With the overall opinion, following could be the possibilty for T Score mapping
English - Mean score should be around 71 and with a Standard Deviation of around 12 giving that most of the 2/3 of the cohort will be between 59 - 83
If the child had scored 88 then the T Score will then be 50+10x(88 - 71) / 12 = 64.16667 ,. Approximation might happen for 5 decimal places.
A perfect score then translate to 74.16667
Maths - Mean score could be around 76 and Estimated Standard Deviation of 12 giving that most of the 2/3 of the cohort will be around 64 - 88.
If anyone scored 98 then the T Score would then T Score could be
50+10x(98 - 76) / 12 = 68.33334
Perfect Score will then tanslate to 70.00
If the same trend continues in next 2 papers we can expect the top score to be in the range of 280 - 285 - One more repetition of 2010. !!!
Any other opinion ???
