[Stressmasta]

im pretty sure i failed the exam ...can anyone approximate what 45% will scale up/down to?

talking about answers now will only drive you self-esteems lower. it's done. get over it and go pepper your angus' for ext 1.

srs

speaks the truth. peppering

15b)
i) real coefficients - roots in conjugates
II) just factorise
ii) for there to be a real root, z-k=0 and kz-1=0 simultaneously. therefore, k = 1 or -1; sub this value in
iv) product of roots; modulus^4 = 1. and they all have equal modulus. therefore = 1
v) use sum of roots
vi) no idea

EDIT: with vi), i had an idea, but not enough time. sum of roots two at a time would give you a value of k^2. you would then use the fact that k=x-y to prove it is greater than something; and it should fall out somehow

easy paper

 

[YoYoWayne]

Shit it was sooooo hard for me T.T
Anyone know how will a 80% raw will be alligned? what about 85% ?

 

[nightweaver066]

Think i'll be happy with my mark

Wasn't a very hard paper nor was it easy. Decent paper overall.

 

[Riaa]

Yeah, it was easier than previous years in my opinion.
Although, i wanted more mechanics questions (my strongest topic).

I thought multiply choice would be a killer like it was in trials so glad it wasn't.
Still multiply choice should be banned in all levels of maths...in my opinion LOL

 

[Shadowless]

That's what i also got
Anybody else get the same????

+1 XD

And why was there almost no mechanic questions T_T.

 

[kliro_10]

i found it alright. there was too much conics and geometry imo and nowhere near enough mechanics. volumes by far hardest question. multiple choice was good but theres nowhere near enough structure with this change to multiple choice. last question wasnt too bad but 15a was challenging.

anyone able to tell me what 75-83 may scale to?

 

[7eleven]

+1 XD

And why was there almost no mechanic questions T_T.

Probably the only HSC paper with least amount of mechanics

 

[Bored_of_HSC]

It was alright

 

[unLimitieDx]

Curse that volumes question, figured it out after the exam!

 

[choiyokbao]

decent paper, different format a bit weird but meh, too late to do anything now XD

 

[user16]

what was the locus of the midpoint?

 

[Nws m8]

Probably the only HSC paper with least amount of mechanics

there were two questions on Mechanics bro, dafuq u on abouT?

 

[Ganrulz]

What do you think a 60/100 raw will scale to?

 

[deswa1]

Solid paper. I confirmed dropped 13 marks so hoping for 85/100 though I could get heaps below that with sillies and stuff lol.

I think at the start I was too careful and slow- my setting out for Q11 is beautiful etc. I tried to be careful with restrictions but I probs missed some of those as well.

Dude do you know how to read? He said "least amount" not none.

 

[Raolan]

There was one mark in the multiple choice.

The other wasn't Mechanics, it was 3 unit, unless you want to classify 3 unit applications under mechanics.

 

[hipoppo23]

Lost all the marks on geometry. Rest were good, Q16 c i) took me a while lol
