For some reason I thought of the 3B's and 3C's as 6 total and work from there. Ahh such a blunder yeh your method makes sense now :/

Good to hear. I have a vague idea about the topic and it didn't seem TOO difficult lol

I got 27 for part (i) (yay me, I thought of it in the same way) However for part (ii) I got a slightly larger number I believe. The first 3 has 6!/3!3! ways = 20... and then its this cubed for the other 2 sections of 3? Explain your method because I don't think this was right :/

Ahh thought of the other question I'm unsure about. It's the combinations question (A's B's and C's in certain order) Anyone?

That's what I did, I squared later haha something seemed familiar. Yes originally making it in terms of x^2 is much neater

Yes I do remember something along those lines but I don't remember if I made it in terms of x^2 I'm pretty sure I did but for some reason I don't think I ended up getting the required answer, oh well.

I understand. Wish I had known that for the exam that would've been easy haha

Ahh I see yes that makes sense. And is this known as a telescoping sum?

Ahh ok sorry a misunderstanding... How did you show that 4p^3=qr^2 in the roots of multiplicity I think I got most of the way there..

Personally I don't understand the maths behind parts (ii) and (iii)... :/

Since I was limited on time on the last question, I could do part (i) but skipped until (iv) which I got :v [e] PM'd you for the exam my cousin wants to see it

Wow I guess they wanted revenge by killing us with telescoping sums :evilfire:

Post all the specific question on a CSSA thread I got. Poll there as well :thumbsup:

Haha well good luck then!! Anyone with questions about the paper I might be able to answer? Mechanics kids anything?

I'm not quite sure my teacher never supplied me with the 2013 paper

I have a thread for the CSSA paper on a discussion of all questions :P

Anyone who has done mechanics how were the questions?

From memory I think I do remember using the angle at centre theorem, but not sure about the cyclic quad I think I proved either similarity or congruence don't remember. Cyclic quad does sound like the way to go nice job :D Ahh yes the sine rule I never saw that damn that sucks :/ Anyways it is...

To all those who did the Catholic paper today... Personally I found the test of a reasonable difficulty. From the multiple choice I struggled a little with Q10 but I think I got it :/ Question 11 to 15 was relatively straight forward except for part (ii) of the polynomial multiplicity...

I just got 337 :v. I've played about 2 weeks but not constantly lol. My progression went as follows: 1, 15, 47, 52, 70, 103, 152, 172, 210, 255, 310, 337 (yesterday!) It took me about 10 minutes to get it, so annoying. Also had half the people in my free looking over :uhoh: PS. I haven't...
