lol dude they arent false rumours. If I went to james ruse and came first in 3u maths, you cannot tell me that im going to be expecting below 100. Trends are quite consistent for most of the top rank schools, and if they do vary, it is very slightly, so deswa1s statement is quite accurate
IF you go to James Ruse college it's because you're extremely intelligent to be able to get in. Not just, oh hey let's go to James Ruse, I'll automatically get in and get 99... Not how it works lol. If a kid capable of going to James Ruse doesn't go into JR college, he/she can go to a school in the 600s and still come first and score 99+, they just have to be motivated enough. So no, his statement is both correct and incorrect, and my statement is also correct. Please think of the scenario logically.
If you can come first in James Ruse 3u maths, you can come first in a majority of schools throughout the state. Socially, that's right that you'd expect below 98 or so, but things do change and this year we may have a genius doing 3u maths that may beat JR college.
EDIT:
First in 3u is from 42nd school in the state.
