Binomial probability is generally easier than perms and combs. But I have trouble with this whole probability topic. but binomial theorem etc. best topic. and Nws m8 -, if its "nothing" for you m8. expecting a state rank. Also, i think 4u kids are expected to get 95+ in 3u. (if they are...

screwed for circle geo + perms and combs. nohopeinlyf.

you don't need to study in year 11 to get 90+ atar

this. thanks :)

http://www.wolframalpha.com/input/?i=3x%5E4+%2B+4x%5E3+-12x%5E2 ^ looks like that

I'm 3u. i rated 10/10. but mainly cus I'm a stupid knt.

ahah, yeah "similar" except prolly with I^2 and complex numbers etc and stuff that REQUIRE 4 unit knowledge. but def wasn't similar to other Q10. they probably just did that because the rest of the test was fairly "generic". Bos loves trolling.

ohh right. policies essay was good for me :) but meh, just glad hsc is almost over. only 2 for tests. ahhhhh the dreaded physics. (I shall get fb back the day after phy finishes)

if it says show or something, you show every step, other than that, do it as fast as you can. don't think you are marked down for that. In fact, if you check marking guidelines for maths, its like "3 marks - correct solution".

ohh wait. I forgot you do 4u.

Re: Oh god.... Will I get marked down for writing this as my reason for similar trian FKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK. lost another mark. this is bad. fk bos. can any one confirm? do we need equilangular? cambridge just was "AA" nothing else

I can assure you It was not 3 unit. But I think question 16 was a tad harder than past HSC Q 10s.

LOL this guy. inb4 state rank for 2u. It was okay, how was eco + 2u? I don't think 3u will count into my atar lol, so doesn't matter. I'm still feeling shiz about that BOP essay. can't believe I fucked it up when I could ev gotten around 17 or 18/20 for that :(

it looked like a normal quartic with an upside down parabola in the middle

LOL 4u scaling is overkill man some guy uploaded his raw marks last year. 59/120 to like 86 or 89 aha. mid 70s/100 should be around 95 right? But I guess new format so things will change. Man 3u, Ill be happy with band 6 :D. perms and combs :( I suck at the hard ones. hope the test is packed...

hes gonna come 1st in state. all hail.

yeh, i think so. we had to sub in y = 1 or something. I thought that was a nice question. AND FKKK YESSS. ITS RAINING <3 srsly, hope i didn't make any stupid mistakes. fml. so paranoid.

LOL. i was JUST about to ask you haha. It was good man, left out 1 mark in last question to check paper and eliminate most sillies. hopefully 98/99 raw :) --> which will scale to 95 :P how was 4u? was it difficult compared to last year?

I think they will penalise. It wasn't a question 16 for nothing. 1/2 without reasoning prolly.

yep, easiest and most efficient way of doing that question.
