Anyone ready for the 4 unit test? I still haven't touched harder 3 unit or mechanics opps. Getting conics down atm tho :p I heard you only need to be in the top 90% to get scaled up in 4 unit?

Nop, not yet. Will worry about it after english.
I haven't done touched those two topics either :(

^ hopefully..

Does anyone know if a 60ish raw mark aligned/scaled to a 85 HSC last year (2012 paper)?

I don't think you can be ready for 4 unit, after the prelims easy questions, ( in the old paper Q1 -5) you're screwed. Half the stuff in the papers I have never seen before in my Maths life.

Um thats the point, you dont rote learn, and then you can smash the later questions... And some people actually get insane scores, so yeah :)

I'm so fcking ready for 4u, come at me! From previous past papers, I can pretty much get all of Q1-3 all correct, Q4-5 most correct, Q6 1/2, Q7 1/3, Q8 probs 2-3 marks. But theres still some room for improvement. I think I've focussed too much on 3u/4u rather than english tho, so I will need to get back to doing that.

Past papers, look at the questions regarding 3U and mechanics.

But the annoying thing is that all the mechanics questions in HSC seem way to easy. ie. the Banked track ones, ie resolve, then find angle which it stays on track. In books, I've seen ones where it also includes a railing at the end of the curve and they ask about height, etc, etc.

+1

You get hsc papers saying "By resolving forces both vertically and horizontally, show that N=..." - 5 marks

wot

Not going to complain though ;D

Bit of a protip for those conical pendulum questions.

Whenever you see something like "If the particle remains on the surface", most likely they want you to let N > 0.

Q16 predictions?

I'm hoping for inequalities and series for the whole 15 marks

(and Q1 MC probability/permutations and that topic being non-existent everywhere else)

Probability + Inequality.

Actually, they asked that last year hmm...

I'm hoping for some kind of reduction, I can at least scam a few marks of that.

Inequalities combined with recursion b/c I predicted 2012 was probability

Or I wanna see a circle geometry problem. Don't think they will do probability again this year
