2 x 141 is that rare
Today's Bucks free Press tells of a "young academic" who has got 141 in both her 11+ papers. Well done to her, but surely it's not THAT newsworthy? Each year there are plenty who get 141 and presumably there are several who got 141 in both?

The following is based on very rusty math... I'm probably wrong for some of this...Anonymous wrote:Today's Bucks free Press tells of a "young academic" who has got 141 in both her 11+ papers.

141 is a good score! i.e. 2.7 std deviations higher than average.
At the tail ends of the distribution there will be far few people but as you move into the body of the distribution there will be lots.
So relatively there will be alot of 140s and signficantly fewer 141s.
141 on both must mean she is well up in the top end of the distribution.
By my calculations that puts her in the best 0.3% of the population.
With 7000 candidates there could be 20 ish people getting that mark.
The $1M question of course is... is she super smart or super good/tutored(?) at getting high scores at 11+ tests?!
All I can say is "Well done!"

It quite funny reading this as my son is in Year 7 at Grammar School after going to appeal last Jan which was successful (119). He is doing extremely well at school and has commented that there are boys in his class that got 141 in their 11+ but are actually struggling with the work at school......interesting.
