2017 CSSA Maths Extension 1 Discussion

[RuiAce]

No more maths for this block

Thoughts?

Papers were required to be held until today (Thursday 17th) so we can now chat about the questions and the approaches we took. However, please do not share copies of the exam or anything similar!

Lost like 5 marks hopefully no more. Wasn't that hard so kinda disappointed.

The perms and combs was hard and so was the projectile part iii.

Was really interesting
Glad there wasn't much rote learn content (cause I didn't study much) and instead had good problem solving qs

I was pleasantly surprised as i thought it was easier than previous years, however in CSSA tradition it was still a challeging exam. We had 21 marks of replacedment questions though, because we havent done projectile or binomial.

The induction was incredibly easy, the parametrics i thought was difficult, and the circle geo was also difficult.

Yeah the projectile was like one of the hardest on the paper so you got lucky there. I did the circle geo in reading time so it didn't consume much of my writing time

I can't solve that combinatorics problem. Lol.

I can't solve that combinatorics problem. Lol.

Skipped all Perms and combs as well as the last binomial. It was pretty bad from what I've gathered but I found the final question doable bar the final part of binomial. Don't think I got the parametrics either :\ 

Hoping for a decent rank as everyone didn't do great..
