same! yeah, that part A of question 15 had me stumped for a while but I think I worked it out. I found Q16 fine...except that sophie probability one (which ever question that was from). That test only increased my dislike for probability :\

Probability was easy, it's a GP with 4/7 as a, 4/7 x 3/7 as R. Then do sum to infinity.

Re: Thoughts on CSSA 2U Mathematics Exam??

Question 16 was fairly easy for me but for some reason, I didn't see the tan substitution thing in question 15 (the one with the cylindrical thing in the roof) -.- I should have been able to see that. Overall, pretty sure I made a lot of silly mistakes. I think I counted around 4/5 marks lost , though I'd probably lose a lot more marks. That probability question was fine for me, the method was similar to one of the past CSSA papers (I think it was the 2000 paper, question 10). Hoping for 90+% ahah.

Re: Thoughts on CSSA 2U Mathematics Exam??

I've heard that Independent is harder than CSSA.

The new format screws head... seriously... How are we meant to answer Q's
that are given to us simultaneously... Did anyone else pickup the order ???

@Lucas... dude, dw.
Just do past paper questions +
(hint hint) make sure you do more Q's 6-10 than 1-5 in past papers...
trust me :J and good luck

That circle question is the reason why you learn the proofs and derivations of things instead of rote learning :p (at mx1 kids)

Most mx1 students should have seen the proof before.
