Thanks to everyone that attended on the day! Hopefully you guys got some decent practice out of some challenging and interesting questions. The papers are attached below. Please note that they have incorporated some minor feedback on the day so they may differ slightly to the hard copy you have.
Massive thanks to Carrotsticks, Paradoxica, calamebe, jjlim7 and ml125 for helping supervise on the day. Also big thanks to the staff from CQU and iStudy for helping to organise the venue.
We will begin the process of solution writing and marking in the next few weeks and will upload these in due course (before your first maths exam of course!).
In the meantime, if you want any hints/guides on specific questions or just want to discuss the paper feel free to post in this thread. Keen to hear your thoughts on both the papers. Were there any questions you particularly liked? How was the difficulty in general and in comparison to previous years (if you attempted those)?

why everyone skip q16 ;_;
If I am a conic section, then my e = ∞
Just so we don't have this discussion in the future, my definition of the natural numbers includes 0.
Both the papers were challenging and orginal in their own ways. Questions such as the milk one in 3u and non-uniform circular which turned into a projectile were both creative and challenging. Thanks again for an amazing day, never gonna forget being humiliated that much!!!!!
I forgot the projectile motion equations, and I knew how to do the question as well which just makes me even more sad
I did some of 16, like 2 parts.

Would it be right to say for the induction question, in the proving step you are required to prove its true for 2^(k+1) people.
= 2*(2^k)
=2^k + 2^k, but by assumption P1 always wins for 2^k people, hence he must win if another 2^k people are added.
Is that the correct way of doing it because I have no idea imao.

i don't think u can make that assumption; after one turn (or rotation) for 2^k+1 player we get the exact case for 2^k player; as half of the player are removed+starting from same spot because of the fact that it is an even number.
This is very close of the content ive seen in maths competitions lol
still did shit

it seems like the probability of winning on the kth term in dependant on both the amount of cards (n) and the intended turn (k). it doesn't make sense to replace n with k if what im saying is correct.
EDIT:
" Suppose the bag begins with only three cards labelled 1, 2 and 3."
ops i didn't read that part; essentially n is set from what im intending to say above; now it makes sense.

I loved the 4U paper but it didn't seem as difficult compared to the previous years. I had a lot of fun doing question 16 especially.
Honestly if anyone passes either of them, they pretty much can guarantee a state rank. Thank god this is not the hsc lmaoooooo
Loll, we will see next year How hard these can get xd
