Usually end of year 11, start of yr 12.
ah ok

i guess it being a competition and all, they introduce these concepts to separate the students who may have more mathematical knowledge

We havent done perms and combs yet let alone any of the probability in year 11 as my teacher hates it... so I was screwed in that department.

Those are always in there (even year 10) as those skills are based on logic and something you don't necessarily need to be explicitly taught.

I was able to do the first 20, then I had about 3 min left at q21, guessed 21-25, and I couldnt have time to attempt the last 5 :/
I really wanted a HD this year :/

But I guess this was a harder paper, so a HD MAY still be possible (probably not)

Did anyone sit the junior paper this year, last time i did it in year 7 it was a lot easier. This year's test just seemed really difficult, 1-20 were fine, 21-25 were ok, 26-30 i didnt bother. However there was one question on the junior one with some decagon and perimeter question, did anyone find the answer to that?

I can post solutions up to the harder questions I know I got right, (question 25, 26, and 29), if anyone is interested.

Also for the question earlier in the thread, the XYXYXYXY probability one was _____.

ah shit

I was about to guess that randomly, but then I thought perhaps 1/256 looked more legit.

Should have trusted my first instincts lol
