Interpreting year 7 scholarship results (1 Viewer)

[Beyblader]

If a kid scores in the top 5% humanities, top 10% maths and top 25% writing in the Acer scholarship exam for year 7 can you extrapolate that to an approximate percentile equivalent ?

initially I thought top 25% for writing was not very good but then I realised that if only the top 15% of kids sit the scholarship exam and a kid scores in the top 25% of that group, then that equates to top 95th percentile of the the general population (100% -(15%x25%)) which is actually a fantastic result

and top 5% equates to top 99.25th percentile 100-(5%x15%))

is that calculation correct or am I making an error somewhere?

do you think the kids that sit the scholarship test would be mostly top 10%, 15% or 20%?

I think there are some erroneous assumptions made here.
1. That only the top 15% of kids sit the scholarship exam.
- Top 15% or 85th percentile is way too high of an assumption I reckon.
2. That the top x% of a certain selection of kids in the top 15% is necessarily in the (100-x%*15%)th percentile of the general population.

what assumptions would you suggest?

ok I've just read in a scholarship testing book that the cohort of kids that sit scholarship exams is generally composed of the top 20% in their state although theres no source cited for that assumption

The scores to get into 100% scholarship offered , you need to get top bands ether ACER or AAS.
